The Microphone Hanger comes in two parts. How and where you mount
the MIC hanger will determine which parts to use.
Conventional Mounting with Screws
Use the front part of the MIC Hanger only.
Locateasuitablemountingpositionandmarkanddrilltwo3mmholes.
Fix the MIC Hanger into place with screws.
Conventional Mounting with Double Sided Tape
(not supplied)
High quality Double-Sided tape can be found at good retail stores.
Secure the front and back pieces of the MIC Hanger using the supplied
binding screws.
Locate a suitable mounting position.
Apply high quality Double-Sided tape
ontotheatareaoftheMIC
Hanger back piece and then
pressrmlytothemounting
position.

Turning on the Power
Press and hold the Power/Channel Selector.
Operation
NOTE
Low-Voltage/High-Voltage Alert
Ifthepowersupplyvoltageexceeds18VDC,analerttone
sounds and dc HI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,dc Loashesfor5
seconds. The power turns off automatically if voltage falls
below8.5VDC.
Switch your UH7700NB OFF and disconnect it from the power
source, before locating the cause of the power supply problem.
Setting the Squelch Level
Press the Power/Channel Selector momentarily. SqL shows and the
currentsquelchlevelwillash.
Turn the Channel Selector to select the desired squelch level.

11
Operation
Think of the squelch control as a
gate. If you increase the squelch level
to maximum it raises the ‘Squelch
gate’ so only the strongest signals get
through.
If you decrease the squelch level to
minimum it lowers the ‘Squelch Gate’
to the extent that weak signals can
get through.
If unwanted weak and noisy signals
are getting through increase the
squelch level (‘Squelch Gate’) to a
medium level. Now only medium
and strong signals get through.

13
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.
UNIDEN UH7700NB UHF CB Transceiver

14
UNIDEN UH7700NB UHF CB Transceiver
Operation
Standard Operation without the aid of a Repeater station.
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-converts your signal and
retransmits on CH01.

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, turn the Channel Selector.
Group Scan (GS) Mode & Priority Watch
Includes the accessory feature, Priority Watch, which allows you to

Operation
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 radio will continue monitoring the
Priority Channel for activity while listening to the active one.
To deactivate SCAN, press the button.
