IMPORTANT INFORMATION

CONCERNING 80 CH UHF CB RADIO

The use of the Citizen Band radio service is licensed in Australia by the ACMA radio communications (Citizens Band radio stations) Class Licence and in New Zealand by the Ministry of Economic Development New Zealand (MED). A General User Radio Licence for Citizens Band radio and operation is subject to conditions contained in those licences.

The class licence for users and equipment operating in the CB/PRS 477 MHz band has been amended. This radio meets the new 80 channel standard.

In simple terms the same amount of spectrum is available; however, radio transceivers can now operate in a narrower bandwidth and hence use less spectrum. These radios are generally referred to as narrowband or 12.5 kHz radios. By using 12.5 kHz channel spacing instead of 25 kHz, the 40 channels originally allocated can now be expanded to 80 channels thereby doubling the channel capacity and relieving congestion in the UHF CB/PRS band.

Original 40 channel wideband Radios will continue to operate on the original 40 channels, however they will not be able to converse on the newer channels 41 – 80. The newer narrowband radios will be able to converse with all older 40 channel wideband radios on all channels 1 to 40 as well as the newer channels allocated from 41 to 80.

The mixing of narrowband and wideband radios in the same spectrum can cause some possible operating issues of interference and varying levels of received volume.

TX3345 INSTRUCTION MANUAL PAG E 3

POSSIBLE ISSUES

When a new narrowband radio receives a transmission from an older wideband radio the speech may sound loud and distorted – simply adjust your radio volume for best performance.

When an older wideband radio receives a signal from a new narrowband radio, the speech may sound quiet – simply adjust your radio volume for best performance.

There can be interference from a nearby transmitting radio if it is using a channel adjacent to the channel you are listening to. Simply try going up or down a few channels from the currently selected channel. The above situations are not a fault of the radio but a symptom of operating wideband and narrowband radios in the same bandwidth. This possible interference will decrease over time as the population of wideband radios ages and decreases.

Further information and updates are available from the Australian Communications and Media Authority (ACMA) at: www.acma.gov.au and the Ministry of Economic Development (MED), Radio Spectrum Management at: www.rsm.govt.nz

EMERGENCY CHANNELS

The ACMA has allocated channels 5/35 for emergency use only. Channel 5 is the primary Simplex Emergency Channel. Where a Channel 5 repeater is available, you should select Duplex on CH 5.

NOTE: Channel 35 is the input channel for the Channel 5

repeater therefore Channel 35 should also not be used for anything other than emergency transmissions.

TE LEMETRY CHANNELS

ACMA regulations have allocated Channels 22 and 23 for telemetry-only applications and have prohibited the transmission of speech on these channels. Consequently the TX3345 has a transmit inhibit applied to channels 22 and 23.

In the event additional telemetry/telecommand channels are approved by the ACMA, these channels shall be added to those currently listed where voice transmission is inhibited. Currently transmissions on Channels 61, 62 and 63 are also inhibited and these channels are reserved for future allocation.

Selecting Channels

Press the or keys to step upwards or downwards one or more channels. Press and hold to advance through the channels at a faster rate.

TRANSMITTING

Prior to transmitting, always check the channel is not being used. This can be done by either listening or by checking the

indicator is not lit.

To transmit, press the PTT button. Hold the microphone about 5-8 cm from your face and speak at a normal voice level. The microphone is quite sensitive so it is not necessary to raise your voice or shout. Release the PTT when you have ﬁnished talking.

IMPORTANT: Always listen to ensure the channel is free

before transmitting

SQUELCH

The Squelch is used to eliminate the background noise when there are no signals present. The TX3345 features a preset Squelch system. The Squelch sensitivity has been factory set to provide optimum performance in most environments, however the sensitivity can be altered by the user if required, to suit varying environmental situations.

The Squelch can be opened or closed by pressing the

SQL

ALPHA

key. When the Squelch is open, the receiver’s background noise can be heard and

is displayed. When the Squelch is closed, the receiver remains quiet when there are no signals present but an incoming signal will override the Squelch and be heard in the speaker.

To open the Squelch

Brieﬂy press the

SQL

key. A low beep will be heard. If

ALPHA

there are no signals present you will hear the receiver’s background noise.

To close the Squelch

SQL

Brieﬂy press the

ALPHA

key again. A high beep will be heard

and the receiver will become quiet.

NOTE: If an incoming signal is very weak and is close to the

minimum Squelch level, it may become broken or ‘chopped’ by the Squelch action. To prevent this, simply open the Squelch to allow the signal to be heard clearly. Alternatively you can reduce the Squelch sensitivity as described below.

SQUELCH SENSITIVITY

The sensitivity of the Squelch to incoming signals can be set to suit your operating environment. In quiet rural locations a low setting will allow the weakest signals to be received while still keeping the radio quiet between transmissions. In city locations, a higher setting might be needed to ensure the Squelch remains closed when subjected to the higher interference levels often encountered in high density areas.

The TX3345 has nine (9) preset Squelch sensitivity settings labelled SQL-1 to SQL-9. The minimum Squelch setting (SQL-1) is the most sensitive and will allow the Squelch to open on very weak signals. SQL-9 is the maximum setting, requiring very strong signals to open the Squelch. The factory default is SQL-3 which generally provides reliable Squelch operation for most applications.

To adjust the Squelch sensitivity

1. Brieﬂy press the

LVL

key. ‘SQL-X’ will be displayed

DYNAMIC VOLUME CONTROL (DVC)

The modulation level of signals heard on the UHF CB band often vary considerably resulting in noticeable differences in received audio volume between stations. In the past, users have compensated for this by adjusting the volume control for each incoming signal. However with the introduction of 80 channel narrowband transmissions, the diversity in received audio volume has increased even further. The TX3345’s Dynamic Volume Control is designed to automatically compensate for these variations in received audio level to provide a constant audio output level to the speaker.

To select the Dynamic Volume Control:

1. Press and hold the

or keys to select DVCOF (Dynamic Volume Control Off) or DVCON (Dynamic Volume Control On).

4. When ﬁnished, press and hold the

key or wait for

the Menu to time out.

CTCSS & DCS

CTCSS (Continuous Tone Coded Squelch System) and DCS (Digitally Coded Squelch) are Squelch quieting systems that allow several groups of users to share the same channel without disturbing each other. There are three optional tone sets available comprising 38, 50 or 104 codes.

CTCSS and DCS systems apply a continuous low-level low frequency tone to your transmission with a matching decoder at the receiver to control your radio’s Squelch. With CTCSS or DCS enabled, the channel remains quiet to all incoming signals unless they carry the correct tone. When a transmission with the correct tone is received, the Squelch opens and remains open for as long as the signal is present. When the transmission ends, the channel becomes quiet again. Transmissions that do not use the correct tone will not be heard.

The TX3345 allows CTCSS or DCS to be enabled or disabled on selected channels and the CTCSS/DCS tone you select will be used for all CTCSS/DCS enabled channels in your radio.

CHOOSING THE CTCSS OR DCS TONE

Choosing which tone to use will probably be dependent on the other radios you talk to. If you talk to others outside your group who already use CTCSS or DCS tones, you will need to select the tone set and frequency that matches theirs. The TX3345 supports CTCSS 50 and CTCSS 38 tone sets as well as 104 DCS tones. If the users you talk to don’t currently use CTCSS or DCS you can make your own choice.

TX3345 INSTRUCTION MANUAL PAG E 9

Page 10

There is no difference in performance between the different tone sets.

If using CTCSS you can chose either the 50 tone set or the 38 tone set. GME radios traditionally use the 50 tone set, however the 38 tone set is also included for compatibility with other radios.

To switch between the 50 and the 38 tone / set:

1. Switch the radio off.

SCANNING

The TX3345 has a SCAN function that allows groups of user programmable channels to be scanned for signals. Channels can be scanned at 20 channels per second. When a signal is found, scanning will pause on that channel to allow the signal to be heard, then resume scanning when the channel is clear again.

SCAN GROUPS

The TX3345 features two scan groups by default - Open Scan and Group Scan.

Open Scan

Allows any of the installed channels to be scanned for activity. If a busy channel is found, scanning will pause to allow the signal to be heard. Once the channel has been clear for 5 seconds, scanning will resume automatically.

1 - 2 - 3 - 4 - 5 - 6 - 7 - 8

e.g. Scanning channels 1-8 in Open Scan.

Group Scan

Also allows any of the installed channels to be scanned for activity, but in addition, it inserts your Priority Channel into the scan sequence. This means that your Priority Channel will be monitored regularly while scanning to ensure that no calls are missed. Any signals received on your Priority Channel will take precedence over any signals received on the other channels.

Scanning in the Group Scan Mode

When scanning, the radio scans all the channels programmed into the Group Scan memory, with the Priority Channel being scanned after every fourth channel.

If a signal appears on the Priority Channel – at any time – the receiver will switch straight to it and will stay there for as long as the Priority Channel is busy. During this time you can transmit on the Priority Channel in the usual way. Once there has been no activity for 5 seconds, the radio will resume scanning the other channels.

If a signal appears on one of the other channels, scanning will pause on that channel and will remain there while the channel is busy, as long as there are no signals on the Priority Channel. During this time the receiver will continue to check the Priority Channel for signals every 2 seconds, resulting in a series of small ‘breaks’ in the reception of the paused channel. Once there has been no activity on any channel for 5 seconds, the radio will resume scanning.

You can use this method to temporarily remove multiple busy channels from the scan if required.

If the unwanted busy channel continues to delay the scan after the 30 second skip period has elapsed, you can completely remove that channel from the scan group for the duration of the current scan session by holding the

If you prefer, the TX3345 can be re-programmed to have two Group Scan modes or two Open Scan modes instead of one of each.

Your TX3345 can be retailer programmed to convert the Group Scan mode into a second Open Scan mode and vice versa. If you would prefer to have two Group Scan or two Open Scan modes, you should contact your GME retailer to arrange for this feature to be enabled (when using two Group Scan modes the Priority Channel will be the same channel for both scan groups).

When the second Open or Group Scan mode is enabled, the resulting two Scan modes become Scan 1 and Scan 2.

Your TX3345 has a Selective Calling system known as SelCall that operates like a telephone. Your radio is preprogrammed with its unique SelCall Identiﬁcation Number. If this number is called by another radio, your TX3345 will beep to alert you. If you do not want to hear any other activity while waiting on a channel, you can select the Quiet mode. Your radio will then remain quiet to all incoming signals until your SelCall number is called.

Your TX3345 will allow you to store up to ten (10) most frequently called SelCall numbers, with each number being labelled for easy identiﬁcation.

SELCALL IDENTIFICATION NUMBER (IDENT)

Your radio is factory programmed with its own unique SelCall Identiﬁcation Number (Ident). This number identiﬁes your radio from others. Your radio’s own SelCall Ident will be displayed for a few seconds in the lower left of the channel display when you ﬁrst turn your radio on. You will need to make this Ident known to others who may need to call you using SelCall.

NOTE: Although your radio is factory-programmed with a

unique SelCall Ident, you can change your Ident to another number if required (see SelCall Memories on next page).

SELCALL IDENT LABELS

When storing SelCall Idents, you can add labels to each one to make it easier to identify whose Ident you are recalling. In addition, if an incoming SelCall matches one of your stored Idents, the label can be displayed instead of the Ident. To add or display labels, your radio must be in the ALPHA mode. To switch between ALPHA mode and Numeric Mode, brieﬂy press the

SQL

key. ‘ALPHA’ or ‘NUMER’ will be displayed brieﬂy to

ALPHA

key followed by the

the lower left of the channel display to indicate the selected mode.

THE QUIET MODE

Your radio can be set to monitor signals on a busy channel but remain quiet unless it receives its own SelCall Ident. In this way, you won’t be disturbed unless someone calls you. When your SelCall Ident is received, the Quiet mode is deactivated and an alarm sounds to alert you to the call. You can then converse normally on the channel. To use the Quiet mode, refer to the Quiet mode section further below. Note that activating the Quiet mode is not mandatory for SelCall operation. You can still use SelCall on any channel whether the Quiet mode is set or not.

TIP: The Quiet mode overrides the normal Squelch system

to ensure that the radio remains quiet even when the channel is busy. When Quiet mode is set, you may see the

icon appear on the display indicating the channel is being used, however, nothing will be heard in the speaker unless someone transmits your SelCall Ident. Quiet mode can be applied to individual channels so that some channels remain quiet while others are open to all incoming signals.

USING SELCAL L

NOTE: The ACMA requires that cumulative SelCall

transmissions should not exceed 3 seconds in any 60 second period. To meet this requirement with your TX3345 you should not send any more that 3 SelCall transmissions per minute.

To return the call

Press and hold the CALL button for a few seconds until the radio beeps. The callers SelCall will be sent back to the caller.

To cancel the alarm

Brieﬂy press the PTT switch. The alarm will be cancelled and the channel will be open for normal communication. You can now talk on the channel in the usual way.

QUIET MODE

The Quiet Mode mutes the receiver to prevent incoming signals from being heard in the speaker until your SelCall Ident is received. This allows you to monitor a busy channel for personal calls without being disturbed by unwanted signals. Once your SelCall Ident is received, the Quiet Mode is cancelled and all incoming signals are heard in the speaker.

Setting up QUIET mode

To setup the Quiet mode you must ﬁrst ‘tag’ the channels that you want to stay Quiet, then activate the Quiet Mode. Once the Quiet mode is activated, the tagged channels will remain quiet to all incoming signals unless your SelCall Ident is received. Channels that are not tagged will remain open to all signals and will operate normally.

Receiving signals in QUIET mode

• If a normal signal is received on an Open channel (one

that is not tagged with ‘Q’) the signal will be heard in the usual way.

• If a normal signal is received on a Quiet channel, the

icon will be visible showing that the channel is busy, but no sound will be heard from the speaker.

• If your SelCall Ident is received on any channel – Open or

Quiet – the Quiet mode will be cancelled and the alarm will beep to alert you to the call. In addition, the caller’s Ident or ALPHA label will be displayed. All channels will now be open for normal transmission and reception.

If you wish to respond to the caller using SelCall, press and hold the CALL button until the radio beeps. The caller’s Ident will be transmitted back to them causing the alarm in their radio to be activated.

To cancel the alarm on your radio, brieﬂy press the PTT.

Receiving signals while scanning in QUIET mode

• If a normal signal is received on an open channel,

scanning will pause while the channel is busy and will resume scanning 5 seconds after the channel becomes clear. (If you were scanning in Group Scan mode, the radio may switch between the open channel and the Priority channel – this is normal).

• If a normal signal is received on a Quiet channel but your

SelCall Ident is not detected, the signal will be ignored and scanning will continue.

• If a signal containing your SelCall Ident is received on

any channel – Open or Quiet – both scanning and Quiet modes will be cancelled and the receiver will stay on that channel. In addition, the alarm will beep to alert you to the call and the callers Ident or ALPHA label will be displayed. The channel will now be open for normal transmission and reception.

TIP: To ensure reliable SelCall detection when scanning in

the Quiet mode, it is recommended that you restrict the number of channels in the Scan group to 4 or less.

As long as the ﬁrst 4 digits of the SelCall you are sending match those of the radios you are calling, their SelCall alarm is activated as if their full 5 digit SelCall Idents had been received.

To achieve this, the 10 radios you are calling must be programmed with sequentially numbered SelCall Idents.

e.g. 14530, 14531, 14532, 14533.. -->, 14539

Transmitting the SelCall Ident 14531 will only activate the alarm in the radio with the SelCall Ident of 14531. However transmitting 1453A will activate the alarms in all radios with Idents 14530 through 14539 (a total of 10 radios).

If the radios in your ﬂeet do not have sequentially numbered SelCall Idents and you want to make use of this function, you will need to re-program the SelCall Idents in your radios.

3. Press the

or keys to select ‘A’ in the ﬂashing digit

position. This is the special code that will create the Group Call.

GROUP CALLING

The SelCall system includes a Group Call function which allows you to call up to 1000 radios simultaneously. This could be useful in an emergency situation where you may need to transmit a message to a large number of radios in your group.

By default your radio is factory set to allow up to 10 radios to be called at once. If required you can arrange for your dealer to re-program this option to allow 100 or 1000 radios to be called. The following description assumes the default Group Call setting of 10 radios.

The Group Call function works by allowing you to enter a special ‘group code’ into the last digit positions of the SelCall Ident you are sending. The ‘group code’ appears as an ‘A’ when displayed in the radio. When this ‘group code’ is received, it substitutes for all other numbers in that position.

e.g.

Sending Ident 145AA will call 100 radios with Idents 14500 -> 14599

14535.. --> 14595

Call acknowledge in Group mode

There is no call acknowledge when sending group calls. This is to prevent all the radios in your group from trying to respond to your SelCall transmission at the same time.

Storing Group Call Idents

Group Call Idents can be stored in memory in the same way as a standard SelCall Ident.

Receiving Group Calls

Receiving a Group Call is identical to receiving a normal SelCall except that the alarm sound is a LOW tone beep instead of the normal HIGH tone beep. The Callers’ Ident or ALPHA Name appears on the display in the usual way.

IN S TALLATION

The TX3345 main unit is supplied with a slim, U-shaped mounting cradle. The cradle can be screwed or bolted in any convenient location in your vehicle (under or above the dash, on the centre console, etc.) using the mounting slots provided in the cradle. The TX3345 contains a built-in speaker, and should be installed in a convenient location in the vehicle’s cabin as the radio’s loud speaker. Alternatively it can be installed in a less audible location and an extension speaker used instead.

The LCD Controller Microphone comes complete with a mounting clip. Its small size and light weight design allows it to be mounted in almost any convenient position accessible to the driver.

When installing the radio, avoid mounting it close to heaters or air conditioners. Screw the LCD Controller

Microphone’s clip to a ﬁrm surface. Fit the TX3345 into the cradle and tighten the gimbal knobs. Place the LCD Controller Microphone in its mounting clip. Finally, plug the LCD Controller Microphone into the front panel of the TX3345

and the power and antenna leads to the sockets provided on the rear of the radio.

ANTENNA INSTALLATION

It is essential to select a good quality, high efﬁciency, 477 MHz antenna. A poor quality antenna or one not designed for the speciﬁc frequency band you are using will give very poor performance.

GME have a wide range of suitable 477 MHz UHF CB antennas to suit most installations and applications. We recommend contacting your local GME retailer for advice.

Connect to the antenna cable to the rear antenna socket using a PL259 coaxial connector.

Noise Suppression

The inherent design of FM transceivers result in a high level of resistance to ignition and electrical interference. However in some installations it may be necessary to take additional steps to help reduce or eliminate noise interference. During installation, try to route the DC battery leads, the antenna lead or any accessory wires away from the engine compartment, ignition or alternator wiring. If the noise continues, try ﬁtting a suppression kit in which case we recommend you consult an auto electrician for advice speciﬁc to your installation.

Higher frequency electrical interference caused by electric motors can be suppressed directly at the motor terminals.

HIGH VOLTAGE WARNING

The TX3345 has a built-in, high voltage detection system to warn you if an overvoltage situation occurs.

If the power supply voltage exceeds 18 volts DC, the channel display will ﬂash ‘hi dc’ for 5 seconds when the unit is ﬁrst turned ON, or at the time the voltage exceeds 18 volts. In addition, when transmitting, the TX indicator will ﬂash and the transmitter will select low output power.

If the overvoltage warning appears you should switch your TX3345 OFF and disconnect it from the power source before locating the cause of the trouble.

Once the high voltage warning has been triggered and you have ﬁxed the source of the problem, you will need to switch the TX3345 OFF then ON again to reset it.

The power source must not exceed 25 volts otherwise permanent damage may occur to your radio, which may not be covered by the manufacturer’s warranty.

ANTENNA CONNECTION

GME supply a wide range of mobile and base station antennas designed speciﬁcally for UHF CB communications.

The antennas are ﬁtted with a PL259 coaxial plug suitable for connection to the antenna socket on the rear panel of the radio.
