sAFetY InFoRMAtIon

The TX675 is a radio transmitting device.

• When transmitting, keep the antenna more than 25 mm from any part of the

head or body.

• Do not transmit near electrical blasting equipment or in explosive atmospheres.

• Do not allow children to operate a radio transmitter unsupervised.

UHF CB RADIo

The use of the Citizen Band radio ser vice is licensed in Australia by the ACMA

Radiocommunications (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 – 40 as well as the newer channels
allocated from 41 – 80.

The mixing of narrowband and wideband radios in the same spec trum can

cause some possible operating issues of interference and varying levels of
received volume.

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.

Depending on how close your receiving radio is to another transmitting radio,

there can be interference from the 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:

TX675 INSTRUCTION MANUAL PAGE 3

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 channel 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.

TELEMETRY 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 radio has a transmit-inhibit applied to channels 22 and 23.

In the event that 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.

IMPoRtAnt ADVICe

READ ALL INSTRUCTIONS carefully
and completely before operating your
radio and retain this manual for future
reference.

• NEVER connect the radio to a power
source other than the supplied
batter y. This may damage your radio.

• DO NOT place your radio in front of a
vehicle airbag.

• DO NOT use your radio with a
damaged antenna.

• DO NOT attempt to modify your
radio in any way.

• ALWAYS charge your radio at normal
room temperature.

• ALWAYS switch of f your radio where
notices restrict the use of two– way
radio or mobile telephones.

• ON LY use GME approved
rechargeable battery packs with the
supplied charger.

• AVOID storing or charging your radio
in direct sunlight.

• AVOID storing or using your radio
where tem peratures are b elow -20°C or
above +60°C.

CHARGInG tHe BAtteRY

The TX675 is powered by a 3.7V Li-ion battery pack. The battery pack should be fully
charged before being used for the first time or if you have not used the radio for some
time. This will ensure maximum capacity is available.

TO REMOVE THE BATTERY PACK

1. Ensure that your radio is switched off.

2. Hold the radio upside-down.

3. Using your fingernail, slide the battery catch towards the front of the radio to
release the battery then slide the battery towards you. The battery pack should
separate from the radio.

Pull to release

TO REFIT THE BATTERY PACK

1. Ensure that your radio is switched off.

2. Align the slots in the battery pack with the battery guides on the back of the radio.

3. Slide the batter y pack upwards as far as it will go until it ‘clicks’.

Slide to lock battery

CHARGING THE BATTERY PACK

NOTE: While the battery is charging, the indicator LED on the radio will light RED

and the battery icon on the display will animate to show the batter y is charging. Once
the battery is fully charged, the radio’s indicator LED will change to GREEN and the
batter y icon will show the full charge state.
