SELECTING CHANNEL SETS
The GX600A is programmed with three Channel Sets –
International, USA and Canada. These Channel Sets support
various channel and frequency allocations for other parts of
the world. Once you have selected the required Channel Set
for your location, you should not need to change it again
unless you have moved to another country.
When using the GX600A in Australia, the International
Channel Set should be selected.
To change the Channel Set
• Switch the GX600A OFF
• Press and hold the 16 key while turning the GX600A
ON again.
• Channel 16 will be selected and the presently selected
Channel Set will flash on the display as INT’L, USA
or CAN.
• Briefly press the 16 key to cycle through the Channel Set
selections in the following order:
The selected Channel Set becomes active immediately.
• Once the required Channel Set is selected, return
to normal operation by either holding the 16 key or
switching the GX600A OFF momentarily or waiting 20
seconds for the Channel Set mode to time
out automatically.
NOTE: When the USA Channel Set is selected, weather
channels are accessible below Channel 01.
DISPLAY BACKLIGHTING
The LCD display is backlit for easy viewing at night.
Brightness Adjustment
To set the brightness of the LCD backlighting, briefly press
the LAMP key. Each press will cycle the following lamp
illumination settings.
HIGH/LOW POWER SELECTION
To switch between High and Low transmit power, press and
hold the 25/1W key. A high beep indicates High power
(25 watts) is selected while a low beep indicates Low
power (1 watt) is selected. When low power is selected ‘LO’
is displayed.
NOTE: Selecting Channel 16 automatically resets the
transmitter to high power.
WORKING CHANNEL MEMORIES
The GX600A has two dedicated ‘working channel’
memories called Channel A and Channel B. These allow you
to store and recall two often-used working channels. These
memories are accessed using keys labeled CHAN A and
CHAN B. Channel A is also used as the Priority Channel
for the Triple Watch function (see feature description later
in this manual). These channel memories also allow faster
channel switching across the band than would normally be
possible using the or keys. E.g from CH16 to CH67.
Channel A
To store a frequency in Channel A, select the required
channel using the or keys, then press and hold the
CHAN A key for 1.5 seconds. The channel number will flash
then a high beep will be heard as the channel is stored.
Channel B
To store a frequency in Channel B, select the required
channel using the or keys, then press and hold the
CHAN B key for 1.5 seconds. The channel number will flash
then a high beep will be heard as the channel is stored.
To Recall Channel A or B
Briefly press the CHAN A or CHAN B key to switch
immediately to the channel stored in that memory. If the
radio was scanning the scan will be cancelled.
