Training Information
The Thrane & Thrane RT5022/RT5020 VHF radio is designed for “occupational use only” and is also classified as such. It must only be used in the course of employment by individuals aware of both the hazards as well as the way to minimize those hazards. The radio is thus NOT intended for use in an uncontrolled environment by general public. The RT5022/RT5020 has been tested and complies with the FCC RF exposure limits for “Occupational Use Only”. The radio also complies with the following guidelines and standards regarding RF energy and electromagnetic energy levels including the recommended levels for human exposure:
FCC OET Bulletin 65 Supplement C, evaluating compliance with FCC guidelines for
human exposure to radio frequency electromagnetic fields
American National Standards Institute (C95.1) IEEE standard for safety levels with respect to human exposure to radio frequency electromagnetic fields, 3 kHz to 300 GHz
American National Standards Institute (C95.3) IEEE recommended practice for the
measurement of potentially hazardous electromagnetic fields – RF and microwaves
Below the RF exposure hazards and instructions in safe operation of the radio within the FCC RF exposure limits established for it are described.
Warning:
Your Thrane & Thrane radio set generates electromagnetic RF (radio frequency) energy when it is transmitting. To ensure that you and those around you are not exposed to excessive amounts of that energy (beyond FCC allowable limits for occupational use) and thus to avoid health hazards from excessive exposure to RF energy, FCC OET bulletin 65 establishes an Maximum Permissible Exposure (MPE) radius of 3” (0.9m) for the maximum power of your radio (25W selected) with an half wave omni-directional antenna having a maximum gain of 3 dB (5.2dBi). This means all persons must be at least 3” (0.9m) away from the antenna when the radio is transmitting.
Installation:
1. An omni-directional antenna with a maximum power gain of 5.2 dBi must be mounted at least 9.6” (2.9m) above the highest deck where people may be staying during radio transmissions. The distance is to be measured vertically from the lowest point of the antenna. This provides the minimum separation distance which is in compliance with RF exposure requirements and is based on the MPE radius of 3” (0,9m) plus the 6.6” (2m) height of an adult.
2. On vessels that cannot fulfil requirements in item 1, the antenna must be mounted so that its lowest point is at least 3” (0.9m) vertically above the heads of people on deck and all persons must be outside the 3” (0.9m) MPE radius during radio transmission.
Always mount the antenna at least 3” (0.9m) from possible human access
Never touch the antenna when transmitting
Use only authorized T&T accessories
3. If antenna has to be placed in public areas or near people with no awareness of the radio transmission, the antenna must be placed at a distance not less than 6” (1.8m) from possible human access.
Failure to observe any of these warnings may cause you or other people to exceed FCC RF exposure limits or create other dangerous conditions.

1 Radio communication in brief
1.1 Powering VHF
The VHF is turned on by a single press on the ON/OFF/Volume button. The VHF is turned off by pressing the ON/OFF/Volume button for 3 seconds. Always indicated by a count down window in the information display, except if the radio is powered down in distress mode.
Any connected devices (Alarm Panel, Handset, CUs) will be operational only if the VHF is powered.
1.2 Operating VHF radio communication
The VHF is operated by means of a handset. To bring the VHF in transmission mode the handset must be hooked off and the PTT button on the handset has to be pressed. Transmission is indicated by the lighted TX indicator. Receive mode is always reached by releasing the PTT button.
HandsetHandset
hooked on
Transmit and receive is performed on the working channel shown in the telephone display. If the handset is used with an RT5020 duplex radio, received signal can always be monitored in the handset earpiece. With the RT5022 simplex/semi-duplex radio the received voice signal can only be monitored in the earpiece while PTT is released.

1.3 Receiving a call on Channel 16
When you hear your call name in the loudspeaker:
1. Lift the handset.
2. Press the PTT key.
3. Repeat the name of the station calling you and say “This is [your ship’s name].”
4. Suggest a channel other than 16 by saying “Channel [suggested number]”.
5. Say “Over” and release the PTT key to allow your caller to confirm the suggested new channel.
0544

6. Switch to the new channel – for example, channel 71 – and begin your conversation. Press PTT only when you are talking. If you are on a simplex channel (in other words, a channel that can carry only one transmission at a time), always say “Over” just before releasing. With duplex channels (ship-shore calls), the conversation can be two-way as with a normal land telephone calls.
Basic
1.4 Making a radiotelephone call
A radiotelephone call is preferably to be commenced using DSC. Alternatively the following public calling procedure shall be used:
1. Select channel 16 (by pressing ) or other agreed channel.
2. Lift the handset.
3. Press the PTT key and make your call. First, say the name of the station you are calling three times. Then say “This is [your ship’s name”], again three times. Finally, say “Over”.
4. Release the PTT key to listen.
5. When answered, agree upon a channel, switch to that channel – for example, channel 6 – and begin your conversation. Press PTT only when you are talking. If on a simplex channel (in other words, a channel that can carry only one transmission at a time), always say “Over” just before releasing.
1.5 Speaker volume
The volume in the loudspeaker (internal and optional external) is adjusted by turning the VOLUME control. The volume level is visualized in the telephone display. The volume can be adjusted to a mute mode by turning the volume control left (down). If the volume is adjusted to the mute level the VOL LED will flash.
1.6 Earpiece volume
The volume level of the default handset earpiece is adjusted by selecting the Handset Volume menu (4.3.1).
The and buttons are used to adjust the level. The level is indicated in the information/message display.
1.7 Squelch
The squelch level is adjusted by using the squelch control. The actual squelch level is visualized in the telephone display.

0544
1.8 Channel selection
The system is defaulting to channel 16 after a normal power-on.
Channels can be selected using the (increasing to next valid VHF channel) or
(decreasing channel). Channels can also be entered using the numeric keypad.
The active working channel is always shown in the upper display.
1.9 Dual watch
Dual watch is a mode where the priority channel (16) is scanned periodically for a signal while listening on a working channel. Dual watch is activated by pressing the DW button.
The DW indicator is lit while DW is active. Dual watch is deactivated by:
Pressing DW – Continues to receive on the working channel.
Pressing PTT – Transmits always on working channel
Pressing ´16´.
Pressing Replay - Dual watch is terminated while the message is replayed and will then be re-invoked
Selecting a new channel while in dual watch mode will continue dual watch on the new selected working channel, unless a signal is found on channel 16.
1.10 Replay
Replay is a facility built into the product which always will allow the operator to repeat the latest 90 seconds of received voice data to be replayed in the acoustic devices. Received voice data is defined when the squelch is open. This means that 90 seconds of actual traffic could be accumulated over several hours/days.
Basic
If the 90 seconds storage limit is reached the oldest data is simply overridden with the newest received traffic data (FIFO principle).
Activating replay
The front panel has a dedicated replay button. A push on the replay button will bring up a (replay) window in the
information/message display. Holding down replay will drive a counter to be updated in the display where it is determined how many seconds of recorded data is wanted for replay - the last XX seconds of recorded data.
If pressing the replay button in normal receive mode this will still allow the unit to receive audio in the speaker system.
0544
5
When releasing the replay button the replay function will take over the audio system and start to replay the last XX seconds of data received on any channel. The time when the traffic was received and the channel on which it was received is displayed during replay.
Volume control can be used on the replay data to adjust sound pressure in audio devices.
Basic
During replay “— —” is shown in the channel display, to indicate that listening on the live receive signal is disabled in this situation (as well as recording is disabled). If a signal is received on the working channel while replay is activated, this is indicated in the lower left corner of the replay window.
Replay is interrupted when:
Pressing , or
Pressing PTT
Receiving any message in the information/message display
Recorded voice data will not survive power-down of any kind
.
1.11 Dimming
To adjust the light intensity the dim button is pressed. While the dim button is pressed the intensity is changing. Releasing the dim
button will maintain the current light intensity. A renewed pressing of the dim button will change the direction of the light intensity change. If the VHF is dimmed to zero, any key press will wake up the light to a minimum visible at
night. Active text in the information/message display might prevent dimming to zero. It is possible to reduce illumination to zero. If you press a key in this state the light will
illuminate to the lowest illuminated state for 5 seconds, where after it will return to the zero illumination state. If a message is shown on the screen while dimming is set to zero, the illumination is adjusted to the lowest nonzero value.
1.12 Contrast
Contrast of the information/message display (and thereby optimizing the vertical viewing angle) can be adjusted initially by entering the Display Contrast menu. Use the arrows to adjust contrast. The contrast will be set simultaneously during adjustment.

2 Basic DSC operations
When switched on, your VHF automatically monitors channel 70 for incoming DSC calls.
2.1 Menu operation
To operate DSC functionality the menu system is used. The main menu can be activated by pressing . From the main menu all parts of the menu tree can be reached (see chapter: Menu tree).
All menus have a unique hierarchical number. The main menu is the only menu which does not have a number. The number is (to a certain level) displayed in the upper right corner of the screen. If more than 6 items are available in the menu, arrows will indicate if remaining
items are to found above ( ) current items or below ( ) current displayed menu items.
The active menu item is highlighted. A press on or will move the focus.
A press on will select the item which is currently in focus.
A press on any of the numeric keys (1 to 9) in a menu will quickly select the menu item having the corresponding number.
A press on will return to the previous menu window (normally one level up). If is pressed in the main menu, the menu will be turned off.
Selecting the menus for transmitting DSC calls will lead to a sequence of windows (flows). The flow sequences are controlled by the (accept and proceed to next window) or
(cancel and return to the previous window) buttons.
Following a menu hierarchy or a window flow might include a guidance text (e.g. “OK/next”
). Certain windows and lists do not show any guidance texts. These windows can
always be left by (jumping to main menu) or (returning to the previous window).
Basic
2.2 Receiving a DSC call
An incoming call will always be recognized by activity on the CALL indicator – and if more severe (Distress and Urgency calls), also the ALARM indicator. When receiving a DSC call the message will be displayed immediately in the information/message display, if not obstructed by any other operations taking place. Received DSC calls will always be accom­panied by a sound alarm.

Basic
When you are ready to accept the call, lift the handset or press . Your choices handling the particular call will now appear. Follow the instructions.
If an individual call is received it will not be acknowledged before you accept the call.
2.3 Transmitting DSC Calls
All DSC calls are initiated from the DSC Call Menu (1).
When entering a menu item, you will be guided through the call construction. For every call generated you will have the possibility of verifying the call before you transmit it.
2.4 Call a ship station
To call a ship station and suggest a working channel, enter the Station Call menu (1.1) and follow the instructions. Have the ships MMSI number ready if it is not available via the contact list. Please also refer to Section 4.1.2 for using extended sub-addressing.
2.5 Call a shore station
To call a shore station, enter the Station Call menu (1.1) and follow the instructions. Have the shore MMSI number (00*) ready if it is not available via the contact list.
2.6 Direct call to a PSTN via a coast station
This kind of calls requires automatic/semi-automatic support from the coast station, and is available only within some countries. If the service is not available, you will need to make a simple shore station call and request the connection via radiotelephony.
To make a direct phone call to a PSTN or a mobile phone, enter the direct phone call menu (1.2) (PSTN Call) and follow the instructions. Have MMSI number (00*) for a reachable shore station ready if it is not available via the contact list, as well as the public phone number you would like to request.
2.7 Call a group of ships
To call a group of ships enter the Group Call menu (1.3) and follow the instructions. Have the group MMSI number (0*) ready if it is not available via the contact list.

2.8 Create emergency calls
In the category of emergency calls (1.4) you will find the following menu:
Transmitting any of these calls should be done with caution. Please make yourself familiar to the common procedures for using these calls.
Selecting any of the call types will lead to a call establishing flow with maximum flexibility. You should make yourself familiar with the flow sequences, but be sure you do not actually send the message by mistake. In other words, never press the transmit verifica-
tion window if you do not actually intend to send an emergency call.
Designated distress calls are composed entering the menu (1.4.1). From this list the Nature of Distress is selected. A fast method to reach this selection list is a short press on . The call completion is then continued from here. If no nature of distress is selected, but
is pressed for 5 seconds, an undesignated distress is sent.
Distress calls are always transmitted by pressing the button for 5 seconds. After you have transmitted a distress call the VHF is in distress mode (distress call is re-transmitted
once each 3½-4½ minutes). The distress mode can be exited only by reception of the appropriate distress acknowledgement call or if you press for 5 seconds, or if you power off the VHF. The VHF will start up in distress mode after a power failure.

Basic
Each of the logs and each of the calls within the logs have their own possible actions upon selection (e.g. printing).
2.10 Entering your position into the system
Ship’s position and the time for this position are essential to the success of a possible rescue operation. This information is automatically added to a DSC distress call sent from your VHF. Therefore it is important always to keep this information updated. Normally a GPS is connected to the VHF. In case of correct installation this will assure correct updating of position and time.
If your VHF is not connected to an external GPS system, or a malfunction of the GPS connection is detected by the VHF, the VHF will automatically prompt you to update your position manually 1 minute after power-up and then every 4 hours. The position and time can always be entered on your initiative via the Set Position & Time selection in the Settings menu (4.1.1).

3 Your VHF in detail
3.1 Abnormal power-down
If for any reason the main power disappears for a period less than 10 minutes, the VHF will be able to turn itself on when power is resumed (without pressing ON/OFF).
If the VHF was abnormally powered down for less than 1 minute, the VHF will start up with the same settings as before the power failure took place (communication channel, volume, squelch settings, etc.).
If the abnormal power down lasted more than 1 minute the VHF might start up with the settings as they were last time the VHF was turned off normally.
Detail
3.2 Settings
All volume settings are stored as default during the power off sequence.
3.3 Automatic squelch programming
It is possible to attach a squelch level with each channel if particular noisy channels require continuous special squelch setting. If a channel is selected squelch level is inherited from either the global setting or a stored squelch level for that particular channel (default is that all channels are using the global squelch level).
Storing squelch level on a channel is done while listening on that particular channel:
Push the button.
The squelch level is now automatically adjusted to suppress the noise on the channel. While adjusting, noise is heard. The squelch level indicator follows adjust­ment, and finally display the required level. The squelch level is memorized on the channel, indicated by flashing the SQ LED (flashing 3 seconds).
If a channel with a programmed squelch level is selected and the SQUELCH button is turned the programmed squelch level for that channel is removed (global level).
During Dual Watch or Scanning only the global squelsh level is used (as indicated by the squelch level indicator). Channel 16 squelch level is not programmable.
All programmed channel squelch levels are stored during power down and restored during power-up sequence.

3.4 Setting channel mode
The VHF is delivered from factory with both Int. & US channels enabled for selection from the operation menu. Provision of other country regions (channel tables) for selection requires the intervention by an authorized Sailor representative in order to enable such. The operator selection of preferred country region (channel table) is done from menu 4.4.1 (channel mode) and the selected country region is indicated in the front panel display (note: this does not apply to the CA channel table and any custom defined channel tables).
The selected country region is stored during power down sequence. Using the country region BI (Inland waterways) Dual Watch (DW) and scanning mode are not
available.
3.5 Private channels
Private channels can be defined by using the service interface only (distributor/dealer).
Enabled private channels become valid for selection on the front panel. Using the /
will simply make the private channel number appear above the highest numeric channel number. 30 (3x10) private channels are available for each enabled channel mode. Note: In US mode private channels P0-9 will be pre-programmed with the 10 weather channels. In CA mode, P0-2 is pre-programmed with the 3 regional weather channels.
Private channels can be selected using the numeric key pad:
Private channels: Long press on followed by a digit (0-9)
Detail
Leisure channels: Long press on followed by a digit (0-9)
Fisher channels: Long press on followed by a digit (0-9)
Continued activation of the keys ´3´, ´5´ or ´7´ will cause the letters F-, L- or P- respectively to be displayed.
3.6 Duplex channels
If duplex channels are selected on an RT5022 simplex/semi-duplex radio (see chapter: Maritime channels) the VHF will operate in semi-duplex mode meaning that the VHF is operated in simplex mode, but uses two different frequencies to receive and transmit. If a duplex channel is selected on an RT5020 duplex radio full duplex is supported on these channels, meaning that both receiver and transmitter is active simultaneously.

ATIS is mandatory to use in inland waterways on e.g. the Rhine. ATIS is a digital data stream containing ships call sign coded into a DSC-like message, sent over the voice channel each time the PTT button is released. If PTT is continuously pressed ATIS is automatically sent each 5 minutes. ATIS is enabled automatically when BI is selected in menu (4.4.1). For purpose of operator comfort the received ATIS signal on the active voice channel will be muted. The ATIS call sign is programmable from the service interface or from menu 4.4.3. once.
The format of the programmed ATIS code is entered according to the following call sign prefix conversion table:

with the digit 2 entered as the first digit, and the digit 4 as the last digit.
3.8 Transmitter power
Transmitter output power can always be chosen while the radio is active. Pressing the 1W button will toggle the transmitter power between low power (below 1W) and high power (below 25W). The 1W indicator is lit when low power is selected. As a default any channel shift will cause the transmitter power to be adjusted to the maximum power allowed on that channel.

3.9 Channel scanning
Scanning is an extension to the dual watch functionality, by which it is possible to watch multiple channels. It is possible to scan:
All channels in a sequence
A number of selected channels in a sequence organized into individual 3 scan tables
- Scan table A, B and C.
The scan type can be selected from the Scanning menu (3). The DW indicator is lit as well (because the priority channel 16 by default is included in any scan table).
During the scan “SC” is shown in the upper display. If an active signal is found on a channel different from channel 16 the radio remains on that
channel for 4 seconds (but still respecting dual watch requirements), where after scanning is resumed. The telephone display is displaying the active channel.
If an active signal is found on channel 16, the VHF is locked on channel 16 until the signal disappears, where after scanning is resumed. The telephone display is displaying the active channel (16).
While the active scanning window is visible, scanning can be terminated by:
Lifting the handset off the hook
Pressing ´16´ - Channel 16 is used as working channel
Pressing DISTRESS – Initiates DSC distress
Pressing – Working channel is used as before scanning was entered (regardless of carrier state).
Pressing Replay - Message is replayed
Pressing any numeric key - Normal channel entry
If scanning is terminated while no active signal was found, the VHF will receive on the working channel (as it was before scanning was initiated).
If scanning is terminated (handset hook-off) while an active signal is received, the VHF will operate on this channel after termination.
3.10 Creating scan tables
The scanning tables are user configurable. Creating or editing a scanning table by organizing a subset of channels (e.g. Table A) for scanning is done by selecting the Edit Scan Table A entry (3.5.1).
Detail
Private channels (non-numeric identifiers – P, F or L) can be part of a channel table. The number of channels in a scan table is limited to 16. 3 scan tables (A,B & C) can be defined for each enabled channel mode. Scanning tables are stored during the power-down sequence.

4 DSC operations in detail
4.1 MMSI Number
To operate VHF with DSC the equipment needs to be configured with your vessel’s MMSI number. If not configured before installation, the VHF will inform you to program the 9-digit MMSI number at start-up.
The vessel’s MMSI number is programmable from the DSC menu (4.5). It can be pro­grammed only once from this menu after which changing of the programmed MMSI will be possible only through the service interface.
If the MMSI number has been programmed correctly, the number is displayed in the default idle display after start-up.
Detail
4.1.1 Sub-Addressed MMSI
The VHF supports setting the 10th digit of the MMSI number to a non-zero value. This is to be used for being able to individually address multiple VHF’s on board a single vessel (with the same 9-digit MMSI). The 10th digit of the MMSI number can be programmed by the operator. After programming the vessel MMSI number the 10th digit will always be set to 0.
Programming the 10th bit is done via the menu (4.5.6.1) If the unit is configured to a non-zero X10 value, it will only respond to received individual
routine calls matching all 10 digits in the MMSI number. Transmitted routine calls or acknowl­edgements to individual routine calls are using the self-ID with non-zero digit 10.
If X10 is programmed to zero the unit reaction modes, if receiving an individual call with non­zero X10 in the address or self-ID, can be selected using the menu (4.5.6.2).
Selecting 1 Acknowledge non-zero, the unit will receive the call. A call acknowledgement will be returned to exactly the same address as received in the self-ID (default after program­ming the MMSI number). Selecting 2 Acknowledge zero, the unit will receive the call. A call acknowledgement will be returned to address as received in the self-ID, but with X10 set to zero. Selecting 3 Reject call, will ignore the received call.
4.1.2 Using extended sub-address in a calling sequence
Entering the station call menu (1.1) allows you to address an RT call request to another radio supporting the extended address format. If the receiver MMSI is not a coast station (00*), it is possible to enter either 9 or 10 digits in the Enter Receiver MMSI window. Entering 9 digits will automatically set the 10th digit to zero for the receiver address.
All other call flows than RT station call requests to a ship station are not supporting this feature.
It is possible to create entries in the contact list with 9 or 10 digit MMSI numbers, unless they are group station (0*) or coast station (00*) numbers.

4.2 Group MMSI number
If your radio is configured as member of a group(s) it will receive group calls to that group. The VHF can be configured to be part of (up to 10) groups. The group MMSI numbers can
be programmed from menu 4.5.2. The configured group numbers are shown as a list. You can add a group MMSI number by
selecting the <empty> list entry and press . Enter a valid group MMSI and press
. A group number can be changed by selecting the number , edit the number and press OK. A group number can be removed from the list by selecting the number, press ,
delete the number and press .
4.3 Differentiating incoming calls by ringing
tones
Your VHF rings in various ways according to the nature of the call, as shown in the following diagram:

the alarm tone used for receiving a call request of the same type. Calls that are not received as distress calls or calls with category distress or urgency will
always engage the prescribed alarm sound. For any other DSC calls the call sound on reception can be enabled/disabled from a Setup menu (4.3.2).
If you receive a call with an alarm sound, you will always be able to mute the alarm by pressing the button to be able to finish current radiotelephony call. This procedure will not affect the actual call accept procedure.
