Programming the Instant Priority Channel
Press / to select the Priority

Recalling the Instant Channel
Momentarily press the [INST] button 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 p.27 - p.29. 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 the microphone [CALL] Button. A three second ringing tone
will be transmitted.
You may select from 5 types of tones (see p.21).
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.

To cancel DUAL Watch press and hold [DCS/CTCSS/DUAL]. DUAL icon

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.
Standard Operation without the aid of a Repeater station.
UHF CB Transceiver

17
UNIDEN UH7760NB
Operation
Operation with the aid of a Repeater Repeater Station (Duplex).
The signal coming from your radio is received by the Repeater Station
and the re-transmitted at the same time on another channel. This
operation is called “Duplexing”.
For example,
CH01 on Duplex Mode will Receive on CH01 but Transmit on CH31
CH02 on Duplex Mode will Receive on CH02 but Transmit on CH32
etc...
If you transmit on CH01 Duplex mode, you are actually transmitting
on CH31 the repeater station down-coverts your signal and
retransmits on CH01.
Operating the UHF CB Radio in Duplex Mode
For this example we are adopting CH01 as the
channel being used in your area for repeater use.

NOTE
Check with your local Retailer for information on available
repeaters.
Scanning
The UHF CB Radio has a scanning feature
that allows you to search for active channels
automatically.
Furthermore, the UHF CB Radio is designed
to have two types of scanning; Open Scanning
(OS) and Group Scanning (GS), to give you

effectively. Press [SCAN/OS/GS] and
Scanning starts.
The SCAN icon appears.
The scan direction can be changed at any time by pressing / .
Open Scan (OS) Mode
Allows continuous scanning of all selected channels. If an active channel
is found, scanning will stop on that channel. If the received signal ceases,
the unit will wait 3 seconds for the signal to return, otherwise scanning
resumes.
After transmission in scan mode, the unit will wait 20 seconds for the
signal to return, otherwise scanning resumes.
To skip the active channel, press / momentarily. To deactivate
SCAN, press [SCAN/OS/GS].
UHF CB Transceiver

19
UNIDEN UH7760NB
Operation
NOTE
If SCAN is deactivated while on an active channel, the UHF
CB Radio will stay on that active channel. If no channels are
active, the UHF CB Radio will reinstate the starting channel.
NOTE
OS Mode is indicated by the absence of the GS icon.
Group Scan (GS) Mode
Includes the accessory feature Priority Watch
which allows you to monitor the Instant Priority
Channel while scanning (see p.15 for setting
Instant Priority Channel and p.20 to turn on
Priority Watch).
To use GS Mode Scanning, press and hold
[SCAN/OS/GS]. GS icon appears on
the display.
GS Scanning checks the Instant Priority
Channel for activity regularly when Priority
Watch is ON.
If the Priority Channel becomes active the radio will stay on that channel
for as long as the signal is present. If the received signal ceases, Priority
Scanning continues after 3 seconds.
If scanning stops on a channel which is not a Priority Channel, UHF CB
Radio will continue monitoring the Priority Channel for activity
while listening to the active one.
To deactivate SCAN, press the [SCAN/OS/GS] button.

NOTE
If OS/GS Scanning is initiated when there are no channels
programmed in OS/GS memory, an error tone will be
heard and scanning will not start (see Programming Scan
Channels - below).
Add/Remove Channels from SCAN Memory
Select which Scanning Mode you wish to use
