Preventative Maintenance:
Should the unit malfunction or perform poorly, follow these procedures.
Check the power cord and fuse.
Check the VOLUME control setting. Be sure the SQUELCH is adjusted properly.
Possibly the radio is over-squelched.
Check that the transmission line (coaxial cable) is securely connected to the
ANTENNA connector.
Check that the antenna is fully extended for proper operation.
Check that all transmission line (coaxial cable) connections are secure and free of
corrosion.
If the transceiver is completely inoperative...
If there is trouble with receiving...
If there is trouble with transmitting...
Check the CTCSS code.

Setting the FM Squelch
Turn the Unit ON by rotating
the volume control clockwise.
Turn the outer ring of the
control to adjust the Squelch.
You must select a
channel which is not
in use before setting
the SQUELCH
control. (see p.7)
Think of the squelch
control as a gate. If you
turn Squelch fully
clockwise it raises the
'Squelch gate' so high that
no signals get through.
If you turn the Squelch
fully counterclockwise it
lowers the 'Squelch Gate'
to the extent that all
signals get through -
weak, medium and strong
signals and noise.
To set the 'Squelch Gate'
to the desired level, turn
the squelch knob
counterclockwise until you
hear noise. Then carefully
turn the Squelch knob
clockwise until the noise
fades. Now only strong
signals get through.

Operation
Selecting a Channel
Turn the Rotary Channel Selector to
select the desired channel.
For your reference a list of the available
channels, corresponding frequencies and
guidelines for their use is printed on page
10. For Australia, Channels 05 and 35 are
reserved for Emergency Calls.
Transmitting
The uh012sx uses the 40 UHF-CB Channels
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.
(Channels 22
and 23 are for telemetry and telecommand applications.
Transmit is inhibited on these channels).
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 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 uh012sx in Duplex Mode
For this example we are adopting CH01 as the channel being used in your area for
repeater use.
Press to switch Duplex On.
"r" (for repeater) is displayed in place of
the 1st digit of the channel number
indicator. e.g. 01 : normal channel 1
r1 : duplex channel 1
If Duplex is not required - press
again to switch Duplex off.
Only channels 01 - 08 are
available for Duplex.
The uh012sx has a scanning feature that allows you to search for active channels
automatically.
Press and Scanning starts.
Allows continuous scanning of all channels in ascending order.
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.
To deactivate SCAN, press or the PTT button on the microphone.
Check with your local Retailer for
information on available repeaters.
If SCAN is deactivated while on
an active channel, the uh012sx
will stay on that channel. If no channels
are active, the uh012sx will reinstate
the starting channel.
