MIC Jack
Before connecting the Microphone Jack decide if you need to use the
Extension Cable - simply connect the MIC plug into the jack end of the
Extension Cable
Push the MIC plug or Extension Cable plug into the MIC jack of the radio
until the connection locks into place. Gently tug the MIC or Extension
Cable cord to test that the connection is locked. Use the rubber cover
which is on the cord to seal the MIC jack entry from dust.
Disconnecting the MIC from the MIC Jack
Pull back the rubber cover and move it down along the cord. Using the
at blade of a screwdriver or similar object carefully push the lock tab of
the MIC plug towards the MIC cord and at the same time tug on the MIC
cord to draw back the MIC plug.

Turning on the Power
Press and hold the [POWER] button.
NOTE
Low-Voltage/High-Voltage Alert
If the power supply voltage exceeds 16VDC, an alert tone
sounds and HI DC ashes for 5 seconds. The power source
must not exceed 25VDC otherwise permanent damage
may occur to your radio, which may not be covered by the
manufacturer’s warranty.
If the input voltage falls below 10VDC, LO DC ashes for 5
seconds. The power turns off automatically if voltage falls
below 8.5VDC.
Switch your X76 OFF and disconnect it from the power source,
before locating the cause of the power supply problem.

Setting the Auto Squelch
The Squelch function is the radio’s signal lter. It determines when the
radio’s speakers turn on, based on the strength of received signals.
This avoids background noise and undesired signals constantly coming
through the speakers.
The Auto Squelch feature has an Off setting and 9 preset squelch levels:
oF (off) - squelch is fully open to noise & signals. Equivalent to Monitor Mode
1 - max sensitivity (min squelch): Weak (distant) signals can open the squelch.
5 - med sensitivity (med squelch): Medium and strong signals can open the squelch.
9 - min sensitivity (max/tight squelch): Strong/nearby signals can open the squelch.
It requires no adjustment.
1. Press [SQL].
The squelch setting ashes.
2. Press / to change the setting.
3. Press [SQL] again to store the setting.
Monitor
The Monitor mode is basically the
squelch function turned off.
Press and hold [SQL] to open the
squelch and receive all weak signals.
Press and hold [SQL] to cancel.

Operation
Programming the Instant Priority Channel
Press / to select the Priority
Channel you prefer. Press and hold [INST]
button on the microphone for 2 seconds to
store the new setting. PRI icon appears
for this channel. By default the road channel,
CH11, is the instant priority channel.
Recalling the Instant Channel
Momentarily press the [INST] button on
the microphone at any time to return to
the Instant (PRI) Channel. Press [INST]
again to return to the previous channel.
EMG (Emergency Button)
Press [EMG] to toggle between the current channel and the emergency
channels 05 and 35.
In EMG mode CH 05 and CH35 ash, and the EM icon displays.
NOTE
When in EMG CH05 or EMG CH35 mode, the / ,
[INST], [DCS/CTCSS] and [SCAN] buttons are disabled.
Press [EMG] again to exit EMG mode and return to the
current channel.
Call Function
Press and hold the microphone [CALL] button. A three second ‘wake-up’
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.

Operation
DUAL Watch
Dual watch will continuously monitor the Instant channel no matter what
other channel is on (see Programming the Instant Priority Channel p.15).
Press and hold [DUAL]. DW icon appears and a short tone beep is heard.
To cancel DUAL Watch press and hold [DUAL]. DW icon disappears.
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.

17
UNIDEN X76
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
1. Select a channel you wish to use in Duplex (Repeater) Mode.
Only channels 01 - 08 and 41 - 48 are available for Duplex.
2. Press and hold [MENU]. DUP icon
appears, indicating the current
channel is now in Duplex mode.
3. Press and hold [MENU] again on the
repeater channel to disable Duplex mode.
NOTE
Check with your local Retailer or ACMA (AUS) / RSM (NZ)
website for information on available repeaters.

UNIDEN X76
Operation
Scanning
The UHF CB Radio has a scanning feature
that allows you to search for active channels
automatically.
Furthermore, the UHF CB Radio provides two
memory groups to scan from; Open Scan group
(OS) and Group Scan group (GS), to give you
exibility. Channels can be added or removed
from the memory groups, see p.20. Channels in
memory are indicated by the Micon.
Press [SCAN] and scanning of the current
memory group will start. SC ashes during scan.
The scan direction can be changed at any time by pressing / .
Open Scan (OS) Mode
Allows continuous scanning of all channels. By default, all channels are
stored in the Open Scan memory. During Scan, 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 activate or deactivate SCAN, press [SCAN].
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.

UNIDEN X76
Operation
Group Scan (GS) Mode
Allows scanning of channels added into the Group Scan memory. By
default, the GS memory is empty and channels need to be added before
GS scan can be activated.
To use GS Mode, press and hold [OS/GS].
GS (or OS) appears on the display.
Group Scan 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 Priority Watch On or Off).
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, the UHF
CB Radio will continue monitoring the Priority Channel for activity while
listening to the active one.
To activate or deactivate SCAN, press [SCAN].
NOTE
If GS Scanning is initiated when there are no channels
programmed in GS memory, an error tone will be heard and
scanning will not start (see Add/Remove Channels from OS/
GS Scan Memory, p.20).

The Priority Watch setting ashes.
2. Press / on the Remote SPK/MIC
to change the setting between ON or OFF.
3. Press the PTT button to save &
exit from the menu mode.
NOTE
If SCAN is deactivated while it is tuned to an active channel,
the UHF CB Radio will stay on that active channel.
If none of the channels are active, the UHF CB Radio will
reinstate the scan start channel.
Add/Remove Channels from OS/GS Scan Memory
Select the scan mode (OS or GS) you wish
to add/remove channels from scan memory.
Select the channel you want to add/remove.
Press and hold [MEM] to add/remove.
The mem icon appears or disappears
and a short tone sounds.
