SQUELCH

The squelch is used to eliminate any annoying background noise when there are no signals present.

Think of squelch as a gate. Turn [SQ]

fully clockwise. This raises the "Squelch Gate" so high that only the very strong signals can get through.

Turn [SQ]

fully counter clockwise until you hear a hiss. This opens the "Squelch Gate" so that everything gets through noise, weak signal, and strong signals.

To set the "Squelch Gate" to the desired level, turn [SQ] counter-clockwise until you hear noise. Then turn the [SQ]

clockwise just until the noise stopped. Now only the desired signal can get through.

If an incoming signal is very weak there is a possibility that you will have a choppy or broken reception, due to the sensitivity of the squelch. In this case, simply rotate the [SQ]

clockwise

until the weak signal is heard clearly.

USING A REPEATER CHANNEL

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 (i.e. a Tall Building) that partially blocks your transmitted signal, the possibility of the other radio receiving the signal is very slim. Valleys, metallic structures, etc., tend to act as a screen between radios.

With Duplex operation, the signal coming from your radio is received by the Repeater station and then re-transmitted at the same time on another channel.

Your

uh073sx is designed with duplex capability on Channels 1 to 8. When any of these channels are set to operate in duplex mode during transmission, the uh073sx automatically sends the signal at a frequency 30 channels above the original in order to access the repeater station. After transmitting, the radio reverts back to its original operating frequency.

For example:

1. CH01 is on Duplex Mode

- will receive on CH01 but Transmit on CH31

2. CH02 is on Duplex Mode

- will Receive on CH02 but Transmit on CH32, etc….

Refer to UHF Channel & Frequencies table on page 20.

TO OPERATE uh073sx IN DUPLEX MODE

Eg. CH01 is being used in your area for repeater use.

SCANNING

The uh073sx has two types of scanning; Open Scanning (OS) and Group Scanning (GS).

Scanning allows you to search for active channels programmed in the OS or GS memory.

To initiate scanning;

1. Assuming the unit is on CH17 when switched on.

2. Press and scanning starts. Scan icon flashes during scanning.

Open Scan (OS) Mode (the absence of GS icon indicates that the unit is on OS mode)

Allows continuous scanning of channels stored in the Open Scan (OS) memory. If an active channel is found, scanning will stop on that channel.

The factory has preprogrammed all the 40 UHF channels into the Open Scan channel memory. However, you can change or customize the channels by following the steps on programming Scan Channels on page 15.

Example: CH40 becomes active

If the received signal cease, the unit will wait for at least 3 seconds for the signal to return, otherwise scanning resumes.

To skip the active channel, press momentarily. Scanning resumes.

To deactivate SCAN, press or .

Check with your local retailer for available repeaters.

Press momentarily. The DUP icon appears.

Press again to deactivate the duplex operation. uh073sx will return to simplex operation.

Group Scan (GS) Mode

Allows you to monitor a Priority Channel while scanning.

To use GS Mode Scanning, press the key. .

GS icon appears on the

display.

GS Scanning checks the Priority channel activity regularly.

If SCAN is deactivated while in an active channel, the uh073sx will stay on that active channel. If no other channels are active, the uh073sx will reinstate the starting channel.

If SCAN is deactivated while it is turned to an active channel, the uh073sx will stay on that active channel. If none of the channels are active, the uh073sx will reinstate the Priority channel.

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.

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 uh073sx will continue monitoring the Priority Channel for activity while listening to the active one.

To deactivate SCAN, press the or .
