Call Tone Function (Wake Up Tones)
Press the microphone [CALL/SELCALL] Button. A three second wake up ringing tone
will be transmitted.
You may select from 10 types of tones (see p.22).
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.
DUAL Watch
Dual watch will continuously monitor the Instant channel and the current channel for
activity(seeProgrammingtheInstantPriorityChannel,p.15).
Press and hold [DUAL]. DUAL icon appears and two beeps will sound.
To cancel DUAL Watch press and hold [DUAL]. DUAL icon disappears.
NOTE

•Dualwatchfunctionstopstemporarilywhenreceivingasignal.
•DualwatchfunctionisinvalidinScanmode.
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.

Operation

UNIDEN UH8080NB UHF CB Transceiver
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-converts 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.
1. Press [MENU]. The duplex
 settingashes.
2. Press / to change the setting
between ON or OFF (standard channel
numbering).
3. Press and hold [MENU]tosave&exitfromthe
menu mode.
DUP icon displays when a selected channel
is set to Duplex mode.
