MIC Jack
Before connecting the Microphone Jack decide if you need to use the 2
metre 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

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 X66
Operation
Operation with the aid of a 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.

Scanning
The X66’ Scanning feature allows you to search for active channels
automatically.
There are 3 scanning modes;
Open Scan (OS),
Group Scan (GS) and
Master Scan (M.SCN) (a special case of Group Scan).
During SCAN the X66’ only checks channels or frequencies that are in
the SCAN Memory, which are indicated by the M (memory) icon. The
X66’ maintains two SCAN Memories; one for Open Scan (OS) mode
and the RWKHUIRU*URXS6FDQ*6PRGHWRJLYH\RXÀH[LELOLW\DQGDOORZ

Add/Remove Channels from SCAN Memory
Select OS Scanning Mode. Select the channel you want to store.
Press [MEM]. MEM icon appears and a beep tone sounds.
To remove the channel from SCAN memory, press [MEM] once more.
The MEM icon disappears.
Open Scan (OS) Mode
Open Scan is the default Scan Mode.
All UHF-CB channels have been added to the
OS SCAN Memory for convenience. To add/
remove channels from OS SCAN Memory,
refer to p.24.
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 deactivate SCAN, press [SCAN].
NOTE
If SCAN is deactivated while on an active channel, the
X66 will stay on that active channel. If no channels are
active, the X66 will reinstate the starting channel.
NOTE
OS Mode is indicated by the absence of the GS icon.

UNIDEN X66 UHF CB Transceiver
Group Scan (GS) Mode
GS Mode has CH09 to CH20 in the SCAN
Memory by default. Channels must be stored
to the GS SCAN Memory before group scan
can start.To add/remove channels from GS
SCAN Memory, refer to p.24.
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.24 to turn on Priority
Watch).
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 [SCAN].
NOTE
If a button is not pressed within 10 seconds the UHF CB
Radio will automatically exit the Menu Mode.
