Operation
Recalling the Instant Channel
Momentarily press
[INST]
on the microphone at any time to return to the
Instant Channel. Press
[INST]
again to return to the previous channel.
Transmitting
The UHF CB Radio uses UHF-CB Channels.
NOTE
For your reference a list of the available channels,
corresponding frequencies and guidelines for their use and
selection is printed on page 23. For Australia, Channels 05
and 35 are reserved for Emergency Calls.
Select the desired channel. Press the microphone’s PTT button and
speak normally into the microphone. Hold it approx. 7cm from your mouth.
Release the
[PTT]
button to end the transmission and listen for a reply.
Call Function
Press
[CALL]
on the microphone. A three second ringing tone will
be transmitted. You may select from 5 types of tones (see p.18 for
“Selecting the Call tone”).
NOTE
Current regulations require calling tones to be restricted to
one transmission per minute. If a second transmission is
attempted within one minute then an error tone will sound.
Using Repeater Channels
UHF CB Repeaters are used to retransmit or relay your signal. Repeaters
will extend the range of your radio and overcome the shielding effect caused
by solid obstructions. In normal Simplex operation, your radio transmits on
one particular frequency and receives on that same frequency.
If there is a barrier that partially blocks your transmitted signal, the
probability of another radio receiving the signal is very slim. Hills, tall
buildings, metallic structures,...etc tend to act as a screen between radios.
