BATTERIES

FITTING AND REMOVING THE BATTERY

To fit, unpack the battery and slot it into the rear of the hand-held. Push the battery down until the catch clips into the bottom of the case. The battery is fully secure when this catch has clipped into position. To remove, push the catch upward towards the top of the hand-held. The battery pack will unclip and can then be removed.

ATTERY CHARGING

The battery should only be charged with Sepura Limited approved battery chargers. Failure to use an approved battery charger will invalidate the warranty of the battery and the hand-held.

A range of battery chargers is available that allow the battery to be charged while fitted to, or removed from, the hand-held (depending upon the charger model and hand-held type selected). When the battery is fitted to the hand-held, the battery can be charged via the facility connector located at the base of the hand-held. If the battery is charged with the hand-held switched on, the time remaining to charge the battery to its full capacity is shown on the hand-held’s display.

MOD-06-366

When charging, the colour of the LED on the hand-held indicates the progress of battery charging: orange shows charging in progress, green shows charging complete, red shows charging failure. A fully discharged battery may not provide enough power to support the hand-held display during the initial phases of charging. However, when sufficient power is available, the display will operate.

The battery includes circuitry to protect against damage caused by accidental shorting of the contacts. Once the battery has protected itself, it will not operate again until it has been removed from the hand-held and charged.

The hand-held will warn the User of a Low battery condition by displaying the Low battery Icon and repetitively flashing the Red LED for 1 second at 1 second intervals.

As with all batteries, charging cycles reduce the cell capacity. The battery is specified to have retained a nominal 80% of its original fully charged capacity after 500 charge cycles. Charging must be conducted using a Sepura approved charger.

Batteries have a finite life; they will deteriorate if they are not charged on a periodic basis. Batteries should not be left for more than 6 months without r echarging as the cells will deteriorate and the batteries will not be recoverable.

sepura

The latch on the battery is specified to 6000 insertions (equivalent to 8 insertions per day over 2 years if used every day of the year.

Many professional and consumer products from cycle lamps to mobile phones and laptop computers now use rechargeable lithium-ion (Li-ion) cells because of their small size and high energy density. When charged and used correctly these are reliable and safe. There are some simple precautions that should be observed when charging and using Li-ion packs. The precautions below apply to most/all Li-ion battery packs and chargers.

1. Properly designed Li-ion batteries and chargers contain effective protection circuitry to safeguard the pack during charging and use, but in some very rare circumstances of internal cell failure during charging, the protection circuits may be ineffective and the pack may overheat. To minimise the chance of this causing further damage, Li-ion battery chargers should be used in well ventilated areas away from combustible material. For example, don’t charge your TETRA battery, mobile phone battery or laptop battery with the battery and charger very near to curtains, soft furnishings, paper or other combustible material.

2. Copy batteries are available for many products, particularly mobile phones and more recently TETRA radios, including those made by Sepura. These may be cheaper than approved batteries, but may not include protection features used in the approved battery, so may be less safe and should not be used.

3. Use only Sepura approved chargers for charging Sepura products. Non-approved chargers may incorrectly charge the battery, leading to premature failure, or render the battery potentially unsafe.

4. Sepura batteries are designed to be rugged and to give good service. However, as is the case for all Li-ion batteries, it is possible for extreme mechanical damage to weaken the internal structure of the cells within the battery. Therefore, if the battery casing shows signs of severe damage (not the minor scratches and bumps of everyday use), or has been subjected to major mechanical abuse, do not continue to use the battery.

In order to operate the following components are required:

• TETRA Mobile/Gateway Transceiver Unit

• Power Cable Assembly

• An Antenna

Optional accessories that may be included:

• Mobile Console Unit

• Mobile Integral GPS Unit

• Applications Interface Unit (see next page)

The Mobile or Gateway should be installed by following the instructions in the Installation Guide.

AUDIO ACCESSORY CONTROL

The mobile will support up to 4 audio accessories, and these can be any combination selected from:

• none or one hands-free kits

• none to four handsets

• none to four fist microphones

The Mobile/Gateway supports the concept of a single controlling audio accessory for a call. The controlling audio accessory is the one in control of the call, and the only one on which the microphone becomes active.

When a fist microphone or hands-free kit is used, the received audio is directed to the loudspeaker connected to the mobile unit. When a handset is used, the received audio is directed to the handset earpiece.

The controlling audio accessory is normally the Remote Microphone used in conjunction with the Loudspeaker, i.e. the hands-free kit or ‘Public’ mode. If the user requires that a different accessory should become the controlling accessory this may be achieved by pressing the PTT button on that accessory or by taking that accessory off hook. If the new controlling accessory has an earpiece then normally this is used for received audio instead of the Loudspeaker (‘Private’ mode).

When in ‘Private’ mode the user can switch to ‘Public’ mode by pressing the hands free soft key if configured. Taking a handset off hook, or using its PTT will return to ‘Private’ mode.

While the controlling accessory is not the Remote Microphone, the user may switch to another accessory by pressing the PTT button on that accessory. Taking that accessory offhook does not change the controlling accessory. This allows a second user to listen to received audio on another accessory.

If the controlling accessory is placed on-hook this will clear the call unless customised differently. Other accessories can be put back on-hook without clearing the call in progress.

TETRA Terminals User Guide

MOD-06-366

All earpiece audio is left on all the time in order that multiple users may listen to the received audio.

The audio presentation for duplex calls depends on the capability of the controlling accessory. With a duplex controlling accessory, duplex calls have a duplex presentation, and with a half duplex accessory duplex calls are controlled using the PTT button.

DUAL CONSOLES AND APPLICATIONS INTERFACE UNITS

The Mobile/Gateway unit supports the connection of up to two console units. Each console unit can be a standard console, complete with keypad and display, or an Applications Interface Unit, which is similar to a console but which does not have a keypad and display. This enables the mobile to support the connection of up to four audio accessories.

If two consoles are fitted, they both display the same information. This makes it possible for a user to move from one console to another without having to take any special action. If two users are using the same mobile, then operational procedures are required to ensure that the actions of the two users do not conflict.

On some configurations it will be possible to have a hands-free kit attached to each console. If this is the case, only one of the remote microphones will be live during a call. The remote microphone which is live will be the one attached to the console which accepted or made the call or switched the call to hands-free.

NAVI-KNOB™ AND MODE BUTTON

All Sepura terminal products use a Navi-knob™ and Mode button to access and select the most frequently used terminal features. The Navi-knob™ is a continuous rotating knob that in its normal mode adjusts the volume. The Mode button also serves as an ON/OFF switch.

On the hand-held terminals the Navi-knob™ and Mode button allow single handed operation by the users.

The Navi-knob™ and Mode button can be used separately and in conjunction with each other depending upon the function required. See Table below:

WHISPER MODE

Whisper Mode adjusts the sensitivity of the microphone to allow “whisper operation.”

To enable, turn the Navi-knob™ or use the volume-down soft key (if programmed) until the volume level display is at its minimum level. Then turn the Navi-knob™ again as if attempting to decrease the volume further, or press the volume-down soft key. The terminal will emit a low-high alert to indicate that Whisper Mode is enabled.

The terminal may be customised in one of the following ways to disable Whisper Mode.

a) turn the Navi-knob™ as if increasing volume, or use the volume-up soft key (if

programmed) until the Volume Level Display shows the minimum level or higher.

b) turn the Navi-knob™ or use the volume-up soft key (if programmed ) until the volume

level display is at its maximum level. Then turn the Navi-knob™ again as if attempting to increase the volume further, or press the volume-up soft key.

In either case the terminal will emit a high-low alert to indicate that Whisper Mode has been disabled

Note: If Covert Mode has been enabled from the Radio Settings menu (see section on Radio Settings) there will be no further increase in the sensitivity of the microphone if Whisper Mode is enabled.

It will be possible to programme a soft key function to toggle between Whisper Mode enabled or disabled.

DISPLAY OPTIONS

In order to make the text and icons on the screen more readable from a distance, e.g., when a terminal is used in a car kit, or is worn on the user’s body, Sepura terminals have a selection of text and icon display options.

NORMAL MODE

The user can select Normal Mode. This displays key elements of the screen information in a small size.

Activation of Normal Mode can be achieved in a number of ways. It can be activated as the default from switch on or it can be switched on or off by the user as they see fit using a soft key (see section on Soft Keys).

LARGE MODE

The user can select Large Mode. This displays key elements of the screen information in a large size.

Activation of Large Mode can be achieved in a number of ways. It can be activated as default from switch on or it can be switched on or off by the user using a soft key (see section on Soft Keys).

If the user chooses to change from Large Mode to Normal Mode or from Normal Mode to Large Mode, the terminal will display the Top Level screen after the mode change has occurred.

When using Large Mode, some prompts or Icons may not be seen on the terminal display.

If Large Mode is used this should be considered when defining the text strings for use on the terminal, so that both Normal and Large Mode prompts will be visible to the user.

For some language variants, only Large Mode operation is available, due to the fonts required to display the characters.

SOFT KEYS

The terminals support a number of functions which can be customised to be accessed quickly via soft keys. All 12 keys of the radio keypad (1 – 9, *, 0, #) can be customised as soft keys, as well as the Green and Red Telephone Keys. The orange Emergency Button is also a soft key that can be used for another function if the emergency function is not required.

Press and hold the key for one second to activate the soft key function. A key click alert is heard after this time has elapsed.

There are many functions that can be programmed on each soft key. As such, it is not possible to describe the functionality of what each soft key will do for specific customer terminals.

Soft key use is very straightforward. There are single action functions that switch on or off or navigation functions which navigate within menus. For functions that have a range of settings, such as volume control or talkgroup select, press the key a number of times until the desired setting has been reached.

If programmed, it is possible to assign a combination of functions to one soft key. On a terminal, a maximum of four soft keys may each be programmed to perform a sequence of up to eight actions.

For special functions such as Transmit Inhibit, the terminals use a “navigate to card” function. The difference with this soft key function is that the user is required to take some additional action once the function has been “navigated to”.

The required additional action will normally be pressing either the green telephone key to activate or the red telephone key to deactivate. Some “navigate to” functions may require additional user input such as when “navigating to” status messages when it may be necessary to enter a number, for example.

TEXT ENTRY AND EDITING

TEXT ENTRY METHODS

Sepura terminals support two mechanisms for entering text: Multi-Tap and Character Selection Box Text Entry using the Navi-knob™. In both methods, the set of characters available for entry can be selected by the user, so that upper case characters, lower case characters, numbers and special characters (e.g. punctuation) can be separated. This gives the user full control over entered text while also speeding up text entry. Note that different language variants of the radio have different character sets.

All text entry and text editing is started in the same way, by pressing and holding the down arrow key. This will place a flashing cursor at the start of the message.

CHARACTER SET SELECTION

The character set is selected by pressing the right arrow key repeatedly until the desired set is shown. The selected character set is displayed at the bottom of the screen. Depending on the software version of the terminal, a character set selection box may be displayed on the left of the display. In this case the Navi-knob™ or the right arrow key may be used to change the character set, and allowing the box to timeout, or pressing the green telephone key selects the character set indicated by the arrow cursor in the box.

CURSOR MOVEMENT

While text is being entered the cursor advances automatically. To reposition the cursor in the text and insert new text, first remove the character selection box by pressing the red telephone key or the up arrow key. While no character selection box is displayed the cursor can be moved around the text character by character by using the Navi-knob™ or by using the up and down arrow keys, which move the cursor line by line. Then use multi-tap or Character Selection text entry using the Navi-knob™ as described below.

MULTI-TAP TEXT ENTRY FROM THE KEYPAD

The user may select a character by pressing the appropriate key from the keypad which has the character assigned to it. The user should press the same key until the required character appears on the screen. For example, on an alphanumeric keypad, in order to enter “YES” the user would press key 9 three times so that “Y” is displayed. The cursor will then move to the right of the Y and the user should then press key 3 twice so that “E” is displayed. The cursor will then move to the right of the E and the user should then press key 7 four times so that S is displayed. The cursor will move to the right of the last character entered.

SECURITY AND PIN CODES

Sepura terminals can be programmed for PIN (Personal Identification Number) activation at switch on. It is possible to program the terminals to enable the user to change the PIN code if required.

There are two PIN codes that are used in the terminal:

• A four digit PIN at switch on.

• A Master Reset PIN (or PUK) of up to eight digits.

PIN ENTRY

At switch on the following screen will appear

Type in the PIN code (four digits) using the terminal’s keypad. As each digit is entered a star (*) will be placed in that digit position.

Press the green telephone key to continue.

The terminal will now switch on and display the Top Level Menu screen

INCORRECT PIN ENTRY

If the user enters the PIN code incorrectly, the following screen will appear.

If the user enters the incorrect PIN three times, the following screen will appear.

If the PIN has been entered incorrectly three times it will be necessary to type in the Master Reset PIN code (eight digits) (or PUK) using the terminal’s keypad. As each digit is entered a star (*) will be placed in that digit position.

sepura

The green telephone key should then be pressed to continue.

If the user enters the PUK incorrectly then it will be necessary to wait five seconds before reentering the PUK .

After the correct PUK has been entered, the action taken by the terminal will depend on whether it has been programmed to support PIN change using the Radio Settings menu. If this is the case the 4 digit PIN will default to 1234 after a correct PUK has been accepted. The user may then change the 4 digit PIN using the PIN Change option in the Radio Settings menu .

If the terminal does not support PIN code change via the Radio settings menu, the terminal will revert to the last known PIN code if the PUK is entered

USER PROFILES

The User Profiles feature is customisable and so may not be available on every radio. If the User Profiles feature has been programmed it allows the user to switch easily between preset combinations of alerts and settings on the radio to match the user’s circumstances or environment.

If the User Profiles feature is programmed there may be between two and ten pre-defined profiles available.

Selecting a user profile may be achieved in one of the following ways:

a) Press the Mode button three times. A Browser box is displayed showing the currently

selected User Profile. It is then possible to scan through all the available profiles using the Navi-knob™. When the required profile is displayed in the Browser box it may be selected by pressing the green telephone key.

b) By accessing the Profiles card in the Radio Settings menu.

c) If programmed, each user profile may be accessed by using a soft key. Please see

section on Soft Keys for further information.

An example of a User Profile is that the terminal could be set for use in a quiet environment (for example a meeting) or if the user is “On Call” when all the audible alerts and backlight would be switched off so that the terminal would also give the impression of being switched off, but in fact would remain fully functional.

When a User Profile has been selected the Radio Settings cards are updated to reflect the settings resulting from the User Profile change. The Radio Settings cards may also be used to override the settings imposed by a change of profile. See section on Radio Settings.

Any of the following alerts and settings may be included in a User Profile:

• Any or all of the audible alerts

• Any or all of the LED alerts and indications

• Any or all of the vibrator alerts

• Reject Incoming Voice Calls setting

• Speaker volume

• Volume of audible alerts

• Backlight operation

• GPS operation

• Covert Mode operation

• Lone Worker operation

GROUP CALLS (POINT-TO-MULTIPOINT)

TALKGROUP SELECTION

This terminal has not yet attached to a group. This could be due to a number of reasons:

1: The terminal has just been reprogrammed. 2: The terminal was attached to a DGNA talkgroup which was

then de-assigned.

Having no attached group could be avoided if a default quick group has been customised in the terminal.

This screen shows that the terminal is attached to talkgroup 591 “Blue 1” in the “Blue” folder. This was the last selected talkgroup.

To attach or change a talkgroup, the Mode button should be pressed once. This selects Talkgroup Selection mode and displays the Talkgroup Selection Box. The Up and Down arrow key may then be used to select the talkgroup folder and the Navi-knob™ may be rotated to select the desired talkgroup. Alternatively the talkgroup may be selected directly by entering its number using the keypad, irrespective of the displayed folder.

Once the desired talkgroup has been found and is displayed on the terminal, the group will attach after a few seconds or immediately if the PTT button is pressed once. The screen should then change as below.

This screen shows the new talkgroup the user wishes to select.

This screen shows the new talkgroup has been selected.

Talkgroups can also be selected using the “Home Group” or a “Quick Group” soft key. “Quick Group” soft keys are a programmable function. It is possible to have up to five “Quick Group” soft keys programmed. The “Home Group” soft key selects the first talkgroup in the current folder. These soft keys can be used while displaying any screen. It is not necessary to press the Mode button before using them.

Another talkgroup selection method is to use the “last requested group toggle” soft key function. This allows the user to toggle to the previously selected talkgroup. This is a programmable function.

CHANGING THE TALKGROUP FOLDER

Folders are used to organise the talkgroup list and to speed up the selection of the user’s most frequently used groups.

If more than one talkgroup folder has been customised, a talkgroup folder may be selected as follows:

Just as for changing talkgroups, press the Mode button once. Then using the up and down arrow navigation key the folder can be changed.

Changing the folder may also change the talkgroup. This will always happen unless the currently selected talkgroup is also in the newly selected folder.

If the user does not wish to use talkgroup folders, or the talkgroup to be selected is not contained within a folder, then the “All” talkgroups option may be selected.

To select the “All” talkgroups list, the Mode button should be pressed once and the up and down arrow keys may be used until “All” is displayed.

Once the talkgroup has been selected and the screen returns to the normal default, the “All” folder information will disappear.

MAKING A GROUP CALL

The sequence of events involved in making a Group Call is as follows:

When a talkgroup has attached, press and hold the PTT.

The terminal status text will change from “Ready” to “Dialling”. This indicates that the terminal is attempting to set up the call.

The next screen change will indicate that the network has accepted the call and is waiting to allocate a traffic channel. This is indicated by the terminal status text changing to “Calling”.

(On a heavily loaded network this message may appear for some time.)

sepura

When a traffic channel has become available the LED will display red (or amber if so customised), and a confirmation tone will be generated to accompany the next screen change. The terminal status text will then change to “Talk.”

The user can now speak into the microphone.

When the user releases the PTT the LED displays green and the terminal status text will change to “Group Call”.

On a network that is lightly loaded it is possible that some of this information will not be seen as it appears very briefly before going into the next screen change.

If the user then presses the PTT again while the call is still active, the LED will again display red (or the customised colour), a varying alert tone may be generated (programmable option) and the terminal status text will again change to "Talk". If there is already someone talking when the PTT is pressed then a warning tone will be sounded by the terminal. During the call, the half duplex microphone (at the top of the radio) is active and all received audio is routed to the half duplex loudspeaker (at the rear of the radio). In order to transmit, the PTT button should be pressed before starting to speak and held down while speaking continues. When speaking has finished, the PTT button should be released and another party involved in the call can then press the PTT button on their radio and speak.

When transmitting, the LED is illuminated red (or amber if so customised). When receiving (i.e. another party is talking) the LED is illuminated green.

When the call has come to an end, the user who initiated the call can either wait for the network inactivity timer to expire, which will clear the call, or press the red telephone key to clear the call. The terminal status text will then return to the default of "Ready…", and a varying tone will be generated. The Top Level screen (see section on Navigating Menus) will be redisplayed.

sepura

RECEIVING A GROUP CALL

When an incoming group call initiated from another terminal is received, this will be indicated by the terminal status text changing to “Group Call” (which is only visible in Normal Text Mode). The LED will flash red, indicating a new call, and a new screen indicating the name of the talkgroup being used, talkgroup folder and the caller’s ID will be displayed. After a few seconds, the LED will stop flashing red and will change to a steady state green.

This screen remains visible throughout the call except when the user selects an option available from the In Call Navigation feature. Only the name will change depending on who is transmitting during the call. When another member of the group is transmitting, their TPI (Talking Party Identity) will be displayed on the screen.

If the ISSI (Individual Short Subscriber Identity) of the transmitting terminal cannot be matched with a Phonebook entry, then only the ISSI number is displayed.

When the call has come to an end the user who initiated the call can either wait for the network inactivity timer to expire, or press the red telephone key to clear the call. The terminal status text will then return to the default of “Ready” and a varying alert tone is generated.

RECEIVING A BROADCAST CALL

A terminal may receive a Broadcast Call. This will be initiated from the Controller. The terminal status text will change to “Broadcast Call” and the Broadcast Call Icon will be displayed.

When the PTT is released, the terminal status text changes to “PTT Call” and the LED displays green.

During the call, the half duplex microphone (at the top of the radio) is active and all received audio is routed to the half duplex loudspeaker (at the rear of the radio). To transmit, press the PTT button before starting to speak and hold it down while speaking. When you have finished speaking, release the PTT button and another party involved in the call can then press the PTT button on their radio and speak.

When transmitting, the LED is illuminated red or amber (depending on customisation) and when receiving (i.e. another party is talking) the LED is illuminated green.

To end the call, either party can press the red telephone key.

Dial modes are configurable, and as such, it is possible that the dial modes will not follow exactly what is described above.

The called party may choose not to accept the call. In this case a message to indicate that the call has been cleared will be displayed on the screen. If the terminal has a colour or greyscale display a large triangle warning symbol will also be displayed.

RECEIVING INDIVIDUAL HALF DUPLEX CALLS

A terminal may receive individual half duplex calls which are either Direct Set Up (no need for the user to respond) or Hooking calls (which require that the user responds). On receiving an individual half duplex Hooking call the terminal will either vibrate or an intermittent audible alert will be generated, or both. On receiving a Direct Set Up call an alert will be generated for a very short time. The terminal status text will change to “PTT Call” and the LED will flash red if the call is a Direct Set Up call, or amber if the call is a Hooking call. The screen will change showing the TPI (Talking Party Identity).

In the case of a Hooking Call the user may choose to answer the call by pressing the PTT button or to reject the call by pressing the red telephone key.

If the call has been accepted, then either party may end the call by pressing the red telephone key.

The terminal status text will then change to “Ready” and a high low audible tone will be generated.

RECEIVING FULL DUPLEX CALLS (TELEPHONE OR TETRA)

On receiving an incoming full duplex call, the terminal will vibrate or generate a telephone ringing alert, or both. The terminal status indication will change to “Telephone” and a CLI box (Calling Line Identity) will indicate the call originator’s identity.

If the terminal can match the incoming CLI with an identity or telephone number in its Phonebook, then the text label associated with the number will be displayed as the CLI.

The user can choose to answer the call by pressing the green telephone key or to reject the call by pressing the red telephone key.

If the user answers the call the terminal status will immediately change to “Completing”.

At this point the call has not been connected, but the user has confirmed to the network that they wish to accept the call. Once the network has finalised the connection, the terminal status will change to “Talk”. The terminal should be held against the head as with a telephone handset or a GSM ‘phone. The user should speak with the mouth near the Duplex microphone and should not press the PTT button.

To end the call, press the red telephone key. The terminal will generate a double high low tone to indicate that the call has been cancelled.

When the call is cancelled by either party, the other party will hear a call disconnect tone indicating the call has ended.

FULL DUPLEX CALLS, RECEIVING AS HALF DUPLEX

Due to operational needs the user may wish to answer an incoming full duplex call as a half duplex call. This could be due to high ambient background noise levels where a full duplex call could pick up too much background noise for clear communications.

Upon receiving an incoming full duplex call, the terminal will vibrate or generate a telephone ringing alert, or both. The terminal status indication will change to “Telephone” (only visible in Normal Text mode) and CLI (Calling Line Identity) will indicate the call originator’s identity.

To answer the call the user should press the PTT button. The terminal status will immediately change to “Completing” and then to “Talk”. The user should then press and hold the PTT while speaking, as for group calls and individual half duplex calls.

To end the call the red telephone key should be pressed. The terminal will generate a varying alert tone to indicate that the call has been cancelled.

MISSED CALLS

If the terminal receives a full or half duplex call and the user does not answer or clear the call the Call History icon will be displayed. The details of the caller’s identity and time and date of the call may then be found by selecting the Call History option (see section on Call History.)

EMERGENCY CALLS

All Sepura terminals are equipped with an emergency alarm button which can be used to make an emergency call if an emergency arises. This button can be identified by its unique orange colour and location.

On the hand-held terminal it is located on the top of the terminal between the antenna and the Navi-knob™. On the Mobile and Gateway it is located on the left hand side of the console below the Navi-knob™.

Emergency Button

To avoid accidental operation of this feature, the emergency button must be held down for a customised period before it operates (usually 2 seconds). When the emergency button is pressed, depending on customisation, an emergency status message is automatically sent to an individual, the dispatcher or the currently selected group, and/or an emergency speech call is set up to one or more users.

The use of the live microphone during an emergency call, when the radio alternately transmits and receives without the user needing to press a key, is also customised by the programming software.

On the colour and greyscale hand-held terminals which are initiating or receiving an Emergency call a large Emergency Symbol will be displayed for the duration of the Emergency call. On the colour terminals the symbol displayed will be red.

Additionally, the mobile can clearly indicate when there is an incoming emergency call by flashing its backlight red. Once acknowledged, the backlight and LED are lit as per a normal call of the same kind for the duration of the call. On initiation of an emergency call from the mobile the display will be backlit amber on the transmit duration of the live microphone cycle and green on the receive duration of the live microphone cycle.

The emergency button can be programmed to react in a number of different ways:

When the emergency button is activated, the terminal can be programmed to transmit automatically for a programmed period of time with live microphone. When the terminal has finished transmitting, it can automatically change to receive mode for a period of time without needing to use the PTT button.

This can be a cyclic operation, when the terminal continuously transmits and receives until reset by either the user or the dispatcher, or it can be programmed as a singleshot “one-transmit one–receive” operation or it can cycle for a number of predetermined transmissions.

When the emergency call is activated, the call goes to the currently selected talkgroup, or it can be programmed to go to a specific address (such as a dispatcher).

When the emergency call is activated, the terminal can be programmed to send an emergency status message (status code 0) to the currently selected talkgroup, or to a specific address.

The terminal can be programmed with various priorities when the emergency button is activated. This would typically be set as a pre-emptive call (Priority 15), so that when activated, even if there is no network resource available, the network will automatically release traffic channel resources for the call.

If the terminal is equipped with a GPS module, it can be programmed to send the current location or last known position of the terminal.

same way as the call was initiated.

RECEIVING AN EMERGENCY CALL

When a terminal receives an emergency call the user does not need to take any action. The emergency call will be received just like any other call except that the terminal status indication will immediately change to “Emergency” (only visible in Normal Text mode), and the screen will display the terminal identity, group identity and an emergency symbol. At the same time the LED will flash red and the LCD backlight will illuminate for a few seconds. Also a high pitched audible alert will be activated leaving no doubt that the call being received is an emergency call. During the transmissions from the call initiator, the receiving terminals will also receive an intermittent alert again leaving the receiving parties in no doubt that this is an emergency call.

The receiving user cannot cancel the call. If the user presses the red telephone key to exit the alarm call they will be brought back into the call under late entry signalling, until the call has been cancelled by the dispatcher.

DIRECT MODE CALLS (DMO)

The terminal may be used to communicate directly with other TETRA radios without the use of a network. This is called Direct Mode Operation. DMO is selected either by using a soft key (depending on customisation) or by activating a card in the Radio Settings menu. The radio leaves the network and tunes to the selected DMO talkgroup. DMO talkgroups are selected in the same way as normal talkgroups.

DMO supports half duplex group calls and pre-emptive emergency calls. It does not support individual calls. Group Calls will be made and received in the same way as for terminals operating in TMO. See section on Group Calls.

Calls using the emergency button can only be configured as pre-emptive emergency calls to the currently selected DMO talkgroup on the radio.

Note: Switching to Direct Mode Operation means communications to the dispatcher and other users on the network are not possible, unless they also switch to DMO and select the same group, or communicate through a Direct Mode Gateway.

When a Direct Mode Gateway is detected by the terminal, a gateway icon is displayed and, if programmed, an audible alert will be generated:

If the terminal moves out of the range of the Gateway, an audible alert will be sounded (if programmed) and the Gateway icon will be removed from the screen.

Group calls can be made via the Gateway to Trunked Mode Operation radios including the dispatcher. Also, a terminal operating in DMO which is in range of a Gateway (icon displayed) may receive a Group call from the network via the Gateway. In order to answer the call the user should press the PTT.

It is possible that a terminal operating in DMO but not within the range of a Gateway may be able to hear the speech of another user who is in range of a Gateway and who is involved in a Group call via the Gateway. In this case the Communication Type Mismatch icon will be displayed on the terminal which is out of range of the Gateway to indicate that the user cannot take part fully in the call. If that user attempts to respond to the overheard speech, any terminals within the Gateway range which can hear will also display a Communication Type Mismatch icon to emphasise to them that the speech is not being routed via the Gateway to TMO users.

If a Gateway receives an individual full duplex call it will send an SDS message to the intended recipient of the call showing “Missed Gateway Call” plus the dialling mode and identity of the originator of the call.

If required, DMO range can be extended by using a repeater. If a repeater is detected, the repeater icon is displayed:

DIRECT MODE GATEWAY OPERATION

Direct Mode Gateway operation (or Gateway Mode) is available only on Mobile and Gateway terminals.

A Direct Mode Gateway links localised Direct Mode (DMO) communications with users operating on a Trunked Mode (TMO) Network. The Gateway will re-transmit information received on the Direct Mode Interface onto the Trunked Mode Air Interface.

Switching to Gateway Mode can also be achieved by configuring a soft key.

Once the terminal is switched into Gateway Mode, it will proceed to check that the DMO channel is not busy and that no other gateways are detected offering the same or an overlapping DMO service that is operating on the same frequency.

sepura

CONFIGURING THE GATEWAY FOR USE

To use the terminal as a gateway, it must be attached to both a trunked mode group and a direct mode group. The direct mode group must be selected once the terminal has been set to work in Gateway Mode.

Before switching the terminal to Gateway Mode, the trunked mode group required for Gateway operation must be selected. This may be the same group as is already in use.

Set the terminal to work in Gateway Mode by using the options in the Radio Settings menu or by using a pre-defined soft key.

The direct mode group to be used with the gateway operation should then be selected. This is done in the same manner as selecting a group when not operating in Gateway Mode (see Note below).

When the terminal is configured, the top level screen will show both trunked and direct mode groups that have been selected.

Trunked Mode Group

Direct Mode Group

The last direct mode group selected for use in Gateway Mode will be remembered by the terminal and will be automatically used as the direct mode group next time the terminal is switched into Gateway Mode. This group may be changed in the normal way using the Mode button and the Navi-knob™ if it is not the required group.

CHANGING GROUPS IN GATEWAY MODE

To change the DMO group on the terminal while it is operating in Gateway Mode may be done by following the same sequence of events as described for changing groups in Direct Mode and Trunked Mode. When a group is changed in Gateway Mode, it is only the DMO group that is changed. The TMO group remains unchanged.

To change the TMO group, Trunked Mode operation should first be selected, then the required Trunked Mode group may be selected. The terminal may then return to Gateway Mode operation. When switching back to Gateway Mode, the last DMO group used in Gateway operation will be automatically reselected.

USING THE EMERGENCY BUTTON IN GATEWAY MODE

If the emergency button is activated on a terminal that is operating in Gateway Mode, any calls that are currently active through the Gateway will cease. The terminal will revert to Trunked Mode operation and initiate an emergency call to the attached Trunked Mode Group. Once the Emergency call has completed, the terminal will remain in Trunked Mode.

Emergency Button

LEAVING A GATEWAY AS A STANDALONE INSTALLATION

If a Gateway is to be left unattended, for long periods of time, or as a permanent installation in a remote location, it is advisable to configure the Gateway as required (select and attach the required Trunked Mode group and the required Direct Mode group) and then power the terminal off using the Mode button. This will save the configuration that has been set up.

Each time the terminal is powered on again, it will re-start with the configuration that has been saved.

This procedure will guard against circumstances such as power failures, which may unexpectedly turn the Gateway off and on again, in an uncontrolled manner, and will ensure that it is always running with the correct configuration.

STATUS MESSAGES

A Status Message is a short pre-defined message that is uniquely identified by a number, the status code.

If the terminal has pre-defined status messages, a message may be selected to send from the Send Status menu or from the status message selection box. To select a message from the status message selection box, press the Mode button briefly twice to display the status message selection box and rotate the Navi-knob™ to scroll through the list of status messages.

PAGING ALERTS

If the Paging Alerts feature is programmed it allows the terminal to act as a Pager when it is in its normal operating mode or when a User Profile has been selected which results in the terminal appearing to be switched off. The Paging Alert is triggered by receipt of a status message which will automatically be displayed.

The status message will be marked with a flag icon to indicate that it is associated with a Paging Alert.

As with other messages in the Message Inbox, pressing the down arrow key displays the time and date when the message was received.

If there is also an associated SDS message to explain the reason for the Paging Alert this will automatically be displayed on the terminal. If a call is in progress the Paging Alert will interrupt it. When the Paging Alert is triggered the user will hear a discordant two tone alarm and the LED will flash amber due to the status message being received.

It is possible to configure the terminal so that if a Paging Alert is triggered while the terminal appears to be switched off it automatically becomes fully operational on receipt of the status message which triggered the Paging Alert.

To stop the alert sounding press any key.

END TO END ENCRYPTION

SECURE COMMUNICATIONS

End to End Encryption has been designed to provide maximum security on communications, whether operating in Direct Mode or Trunked Mode, irrespective of the security level provided by the network.

The shield icon indicates an ongoing group or individual half duplex call is end to end encrypted.

When the terminal is idle, the shield icon also indicates that the selected group is configured for end to end encryption.

A radio that supports End to End Encryption may still be required to make calls that are not end to end encrypted. Half duplex calls to certain talkgroups and individual subscribers may have been configured to be exempt from end to end encryption. Also, all telephone or TETRA full duplex calls cannot be end to end encrypted. When such a talkgroup is selected or the radio participates in a call that is not end to end encrypted, the shield icon is not displayed and a periodic non intrusive audible alert is generated, if configured.

Note that it is not possible to accidentally make a non end to end encrypted call. Every talkgroup or individual subscriber that can be exempt from end to end encryption, has to be explicitly configured into the terminal.

If the message “Security Check Fail” is displayed while making or receiving calls, it is an indication that the terminal has not been configured properly. In such cases, please contact technical support in your organisation.

ZEROISING

A radio that supports End to End Encryption is loaded with sensitive cryptographic keys. To avoid a potential security compromise, these cryptographic keys can be deleted if operation procedures allow.

Please refer to your Security Officer for details on how to Zeroise a radio as well as related operational procedures.

PACKET DATA

The TETRA Packet Data service provides a mechanism to transport IP Traffic over a TETRA bearer, extending TETRA to act as an IP Subnet. This enables application developers to develop in a standardised IP environment with the ability to use industry standard transport mechanisms such as UDP and TCP providing a framework to provide fast and flexible service creation. Packet Data services can only be accessed from the PEI port of the terminal.

Examples of Packet Data Applications could be:

• Database Inquiry

• Mobile Office

• Automatic Vehicle Location

• Resource Management

• Telemetry

• Fingerprint validation

• Still image transfer

• Web Browsing (WAP)

CIRCUIT MODE DATA

Circuit Mode is the most familiar method of data transport to most people. In a circuit switched network, the communication pathway between the sending and receiving parties is fixed for the duration of the call and is not shared by other users.

In Circuit Mode, a communication is obtained between two users by establishing a fixed pathway. The route is established after the calling terminal initiates the call setup procedure by giving the network the addresses. During the connection, the circuit is equivalent to a physical pair of wires connecting the two users.

Circuit Mode Data services can only be accessed from the PEI port of the terminal.

GPS

GPS is available for both the Mobile and hand-held terminals. In the case of the hand-held terminal, Sepura supply a high-sensitivity GPS unit specifically designed for users operating in urban canyon environments.

The behaviour of the GPS function is highly customisable, both from the customisation tool and over the air from a control room application.

The GPS functionality allows for both timed or distance based reporting. The radio may also be customised to send position data automatically alongside Emergency

Calls or status messages.

The destination to which the GPS reports are sent may be changed over the air. If the terminal accepts a change of GPS destination command, it sounds a double low-high tonal alert, (New GPS Destination Alert), depending on customisation. The terminal is sent an SDS message to inform the user of the change of GPS destination.

Finally, if customised, it is possible to enable or disable the GPS function using a card in the Radio Settings menu. In the case where the user has disabled the GPS function the display

will show a warning icon

MESSAGE INBOX

The Message Inbox is used to store received text or status messages. It displays the most recently received message first. The Message Inbox can hold a maximum of 50 messages. When the Message Inbox is full, old messages will be overwritten by new incoming messages. The order of deletion of old messages is oldest read message followed by oldest unread message. Each message is stamped with the time and date of its receipt which are all saved with the identity of the sender.

To keep the Message Inbox to a manageable size it is recommended that messages that have been read are either deleted or saved.

To view the other messages use the left and right navigation keys. The “…” in the lower right-hand corner indicates the message is too long to display on one

screen. Use the down arrow navigation key to see the next part of the message. Inverse video tabs indicate unread messages.

If this message needs to be dealt with at a later date it can be transferred to the Message Store.

SCAN LISTS

A User Defined Scan List (UDSL) is either a list of talkgroups that are fixed, or user definable. Each UDSL will have a default or priority talkgroup with which the user can initiate a call when there is no activity on any of the other talkgroups within the UDSL. Each talkgroup within the UDSL can also be programmed to have one of three different levels of access priority (network dependent), which again can be user definable.

A UDSL is selected in the same way as a talkgroup but when selected, the terminal scans all of the talkgroups in the UDSL. Up to ten talkgroups can reside within a UDSL.

The User Defined Scan Lists menu allows many talkgroups to be monitored at once, and hence calls to be automatically received from any of these groups. If the terminal is customised so that scan lists can be viewed and/or edited, a UDSL icon:

is shown in the menu tabs. If a UDSL group is selected the UDSL icon (above) will be displayed in the right hand corner of the terminal display.

RADIO SETTINGS

The Radio Settings menu allows the user to switch on or off, or adjust, a range of different terminal functions. To access the Radio Settings menu from the top level screen, press the down arrow key, then the left or right arrow keys to select the Radio Settings menu.

The down arrow key should then be pressed to access the menu of different settings available. These are described below. The customisation of the terminal determines which of the options are present. When a valid request is made to select or de-select one of the options a large tick will be displayed on colour and greyscale terminals.

The Radio Settings cards for Covert Mode and Lone Worker which were available in previous versions of the software are not available when User Profiles are a programmable option on the terminal.

LERTS

This function allows all audible alerts to be de-activated and is often associated with Covert Mode enabled (see below).

To enable alerts press the green telephone key. This places a cross in the box (or on some terminals this will be shown by a dot in a circle).

To disable alerts press the red telephone key (remove cross from the box / dot from circle). After programming the default state for this function is alerts enabled. However if the terminal

is switched off with the alerts disabled, alerts remain disabled when the terminal is next switched on.

IBRATOR ALERT

This function allows the user to be alerted to an incoming individual half duplex or full duplex call or an incoming SDS or Status message by the terminal vibrating. To select this option the user should press the green telephone key (cross in box/dot in circle). To de-select, the user should press the red telephone key. The pattern of vibrations will be different depending on whether a voice call or message has been received. (Please see Vibrator Alerts table.) If a voice call is received, the terminal will stop vibrating when either the green or red telephone key is pressed. If the Vibrator Alert has been selected and the user then enables Covert Mode, the Vibrator Alert is switched off and is not re-enabled when Covert Mode is disabled. Once Covert Mode has been enabled, the user may re-select Vibrator Alert from the Radio Settings card if this is required.

The terminal will not vibrate if the incoming call is a group call or direct set-up call or if the terminal is attached to a car kit or charger.

OUDSPEAKER

This function allows the speaker to be switched on or off. The default is speaker on. To switch the speaker off the user should press the red telephone key (remove cross from the box /dot

from circle).To switch the speaker on when it is off the user should press the green telephone key (cross in the box/dot in circle).

Switching the speaker on and off can also be achieved by configuring a soft key.

ACKLIGHT

The default is backlight on (cross in the box / dot in circle). To switch the backlight off press the red telephone key (remove cross from the box /dot from circle).

To reactivate, press the green telephone key. On mobile products, and on some hand-held products it is also possible to adjust the intensity

of the backlight and the key pad illumination by rotating the Navi-knob™.

ONTRAST

The contrast may be adjusted as required by turning the Navi-knob™. This option is only available on colour and greyscale terminals.

TATUS DESTINATION

The Status Destination function allows the user to enter, or subsequently alter, a default status and SDS address that the terminal will always present to the user when a status or SDS message is being sent. The destination address may be that of either a group or an individual.

To edit the default Status destination press and hold the down arrow, then enter the new individual identity using the keypad, and press the green telephone key. To discard changes press the red telephone key. If a Status destination number which is valid for the selected dialling mode is input a large tick will be displayed, but if an invalid number for the selected dialling mode is input a large cross will be displayed and the number will not be stored.

sepura

IRECT MODE

This function allows the user to switch between Trunked Mode Operation and Direct Mode Operation. To activate press the green telephone key (cross in the box/dot in the circle). When Direct Mode has been selected the initials ‘DMO’ are displayed in the top left corner of the screen.

To deactivate press the red telephone key.

In Gateway products, operating mode selection is achieved in a slightly different way. See section on Direct Mode Gateway Operation.

RANSMIT INHIBIT

This feature stops all transmissions from the terminal if the user enters a RF sensitive area such as a hospital, unless the terminal has been customised to continue to support Emergency calls (see section on Health and Safety). To activate Transmit Inhibit press the green telephone key (cross in the box / dot in circle).

To deactivate press the red telephone key.

Activating and deactivating this option automatically transmits a predefined status message informing the control room of the current status.

indicating limited service and the Transmit Inhibit icon (which is customisable) displayed in the top right hand corner of the screen. However if Covert Mode is active at the same time as Transmit Inhibit, the LED will not appear to flash.

CANNING ON

This function allows scanning to be enabled or disabled. See section on Scan Lists and User Defined Scan Lists.

ELP TEXT

Help Text is a text area in the Radio Settings menu which is used to indicate which terminal soft key function is associated with which key. Help Text is normally accessed via its own soft key (Sepura default is normally key zero). With the Help Text displayed, use the up and down arrow key to read all of the text.

IN CHANGE

This option allows the user to change the PIN required to switch on the terminal. Press and hold the down arrow key to change the PIN. The user will be asked to enter the

current PIN, then the new PIN and then will be asked to confirm the new PIN before the change will be made. If all these requests are completed correctly a large tick will be displayed and the PIN will be changed. However if the old PIN is entered incorrectly or confirmation of the new PIN is entered incorrectly, a large cross will be displayed and the PIN will not be changed. Also, during this PIN change sequence, if no keys are pressed for a given period, the terminal will revert to the top level screen and the PIN will not be changed.

SDS

DELIVERY REPORTS

Sepura terminals support SDS reports. This allows the user to request a Delivery Report and a Read Report when sending an SDS (text) message.

There are four basic options available to the user:

• No reports

• Delivery report only

• Read report only

• Both reports

To enable the required settings, with the SDS Report Request page selected, press the up or down arrow keys to move the arrow cursor up or down to select the option required. Press the green telephone key to set the option or press the red telephone key to remove the cross from the box (or dot from circle). Repeat for both options.

GPS

ENABLE

Sepura products have the capability of being fitted with GPS modules. GPS is normally fitted for user safety and/or resource management. GPS activation and deactivation is normally carried out on air by the controller sending the terminal a specific SDS message that addresses the GPS. However, there can be circumstances when having the GPS active might not be appropriate so this option allows the user to switch off the GPS reports.

The default state is GPS enabled.

UICK GROUPS

A quick group soft key allows the user to change quickly to a talkgroup that was previously selected as a quick group, by simply pressing the appropriate soft key.

To associate a talkgroup to a quick group, first select a talkgroup in the normal way from the default screen. Then select a quick group that you wish to associate with the talkgroup from the Radio Settings menu and press the green telephone key.

A different way of associating a talkgroup to a quick group, is by pressing the Mode button, then using the Navi-knob™ and/or the up/down arrow key to select the desired talkgroup and then pressing the PTT.

The new quick group/talkgroup association will now appear on the quick group page.

This functionality is not available on Mobile and Gateway terminals operating in Gateway Mode.

IME AND DATE

This function allows the user to view the current time and date. If configured it will be possible to edit the time and date if required. This may be achieved by first pressing and holding the down arrow key to enter edit mode and then using the Navi-knob™ and/or the left and right arrow keys to move the cursor.

In order to change a number, the cursor should be positioned to the left of that number and the new number should be entered from the numeric keypad. There is no need to delete the old number as it will automatically be overwritten. When the time and date are set as required, press the green telephone key to save the entry. If a valid time and date have been entered a large tick will be displayed momentarily. The new time and date will be visible on the Radio Settings card and the time will also be displayed on the bottom line of the top level menu screen. If an invalid time or date is entered a large cross and an error message will be displayed when the user presses the green telephone key to store them, and the original time and date will not be altered.

SER PROFILES

This function allows the user to select a specific pre-defined combination of alerts and settings for the terminal. See earlier section on User Profiles.

FALLBACK

If a base station loses communication with the rest of the network, then any terminals using this base station continue to operate, but with a reduced service. Entry to and exit from Fallback Mode are indicated by an audible alert and a customisable text message.

If this occurs, the terminal will only be able to communicate with other terminals that are registered on the same terminal site. No inter site communication will be available whilst in Fallback Mode.

When a terminal enters Fallback Mode there are five main indicators;

• the Terminal status bar indicates

Fallback Mode and the yellow warning triangle is displayed momentarily

• the Fallback Mode text box pops up in

the centre of screen for a few seconds.

• the RSSI antenna icon flashes

continuously. On this screen shot it is not visible.

• the LED flashes amber intermittently (indicating limited service mode).

• The terminal generates a warning tone.

When the terminal leaves Fallback Mode:

• The terminal status bar returns to normal (Ready… or similar).

• The RSSI antenna icon stops flashing.

• The LED stops flashing.

• A text box pops up indicating normal operation.

• The terminal generates a warning tone.

Error or Failure symbol

Warning symbol

Emergency Symbol

The Success symbol is only ever displayed in response to an action by the user. If the user selects a function from within the Radio Settings menu or the Change Network card, the large tick is used to indicate that the request is valid and not that the function requested has succeeded.

For some functions such as storing a received SDS message in the Message Store, or saving a new entry in the Phonebook, for example, the large tick will be displayed to indicate that the request has been completed successfully.

The Error or Failure symbol may be displayed in response to an action by the user or as a result of an incoming call. It is displayed to indicate either that an invalid request has been made or that an error or fault has occurred and a request has not been completed successfully.

The Warning symbol is displayed to alert the user to certain conditions, e.g. if the terminal is in Fallback Mode, there are problems with SDS report deliveries, there are unread messages when the user has attempted to switch off the terminal etc.

If a user initiates or receives an emergency call, the Emergency Symbol will be displayed for the duration of the call. Also, if a user receives an Emergency Message the Emergency Symbol will be displayed.

HEALTH AND SAFETY

Use only a slightly damp soft cloth for cleaning all exterior surfaces. Do NOT use chemical aerosol or abrasive cleaners.

To ensure efficient operation, clean the battery contacts periodically with a soft, dry cloth.

Never leave the radio in extreme temperatures (over 55°C), for example behind glass in very hot, direct sunlight.

TRANSMIT INHIBIT

The radio can be switched into Transmit Inhibit should the user enter a RF sensitive area (e.g. a hospital). This mode is indicated by the LED rapidly flashing amber 4 times at approximately two second intervals and the display of the transmit inhibit icon in the top right hand corner of

the screen. In this state, the terminal does not transmit under any circumstances in either TMO or DMO,

except when using the emergency button if customised to do so. The terminal remains on the selected group and in some circumstances can still receive conversations from this talkgroup.

The terminal can automatically send a status message to the customised destination when the terminal enters Transmit Inhibit, and again when it leaves Transmit Inhibit.

Use of the emergency button whilst in Transmit Inhibit is supported; however, the time to set up the emergency call could be increased by a few seconds.

RADIATION PROTECTION

The terminals fully comply with the NRPB specification EN50361 and the ICNIRP guidelines for exposure to electromagnetic fields mandated for mobile phones (2W per kg over a 10g sample).

ELECTRO MAGNETIC COMPATIBILITY

The terminals meet the EMC requirements specified by the ETSI specification ETSI EN 301 489-18.

TYPE APPROVAL

The terminals have been self-certified to RTTE Directive EN 303 035-1 and CE marked to 1999/05/EC.

ACCESSORIES

Only accessories supplied or approved by Sepura Limited are recommended for use with the terminals. Any accessory used that is not supplied or approved by Sepura Limited could cause damage to the terminals and may invalidate the warranty. For safety reasons Sepura Limited do not recommend that accessories be used with a hand-held without first gaining approval from Sepura Limited to do so. When the accessory socket is not used, please ensure the rubber plug is in place to maintain environmental protection.

ADDITIONAL NOTES APPLICABLE TO HAND-HELD

BATTERY SAFETY

Please observe the following before handling batteries: To prevent injury, do not allow metal objects to contact or short circuit the battery terminals. Make sure that the battery terminals do not become dirty. Do not immerse in water or incinerate. If you need to replace the battery, use the Sepura Limited approved battery types.

ATTERY DISPOSAL

Batteries must be disposed of in the correct manner according to Sepura environmental policy. If in any doubt, refer to your supplier or local Sepura Limited representative.

COUSTIC SHOCK

Sepura Limited has engineered an innovative audio solution for the terminal. Duplex audio (for telephone type calls) and the half duplex audio (for radio calls) are directed to different loudspeakers.

Duplex audio is routed to the low power Duplex Earpiece on the front of the radio. A more powerful loudspeaker, situated on the rear of the radio, is used for half duplex audio. This loudspeaker directs the loud audio away from a user’s ear should the user accidentally answer a half duplex call as though it were a duplex call.

WARNING: Hold the radio close to the ear only when making, or receiving, duplex calls.

NTENNA

When fitting the antenna, do not over-tighten. Do not use the radio without the antenna attached.
