IMPORTANT
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 battery. This may damage your
product.
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 off your radio where notices
restrict the use of two-way radio or mobile
telephones.
ONLY use GME approved rechargeable batteries
with the supplied charger.
AVOID exposing your radio to water. It is not
waterproof.
AVOID storing or charging your radio in direct
sunlight.
AVOID storing or using your radio where
temperatures are below -20°C or above +60°C.

IMPORTANT INFORMATION
CONCERNING 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.

PAGE 6 INSTRUCTION MANUAL TX670
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
www.rsm.govt.nz
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.

TX670 INSTRUCTION MANUAL PAGE 7
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
TX670 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.
