Operation

Setting the Squelch

1. To turn the unit ON, rotate VOLUME clockwise. Adjust volume to a comfortable level.

Note: You must select a channel which is not in use before setting the SQUELCH

control on your radio.

2. Think of the Squelch control as a gate. If you turn SQUELCH fuliy clockwise it

raises the "Squelch Gate" so high that no signals get through.

3. If you turn the SQUELCH fully counterclockwise it lowers the "Squelch Gate" so that everything gets through - noise, weak signais, and strong signals.

4. To set the "Squelch Gate" to the desired level, turn SQUELCH counterclockwise until you hear noise. Then turn the SQUELCH clockwise just until the noise stops.

Now only strong signals get through.

Channel Auto Step

To quickly change channels, press and hold ▼ or a . This changes channels at 10 channels per second.

Note: A short tone sounds when you press either T or A and the channel changes.

Another tone sounds when Channel Auto step begins.

Transmitting

The UH*100 transmits on 40 UHF CB channels. For your reference, a listing of all the available channels is printed on the back cover.

1. Select the desired channel, eg. CHOt

2. To transmit, press the PIT switch to activate the transmitter.

Note: Hold the microphone 2-4 inches from your mouth and slightly to one side so that

your voice does not project directly into the microphone. Speak at a normal

voice level. Never raise your voice or shout into the microphone.

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 (i.e. valley) that partially blocks your transmitted signal, the probability of another radio receiving the signal is very slim. Valleys, 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 ot a repeater

The Signal coming from your radio is received by the Repeater Station and then re transmitted at the same time on another channel. This operation is called "Duplexing",

Your UH-100 is designed with the capability to access and use repeater stations. Channels 01 through 08 have the option to operate in Duplex Mode. When any of

these channels are set to operate in duplex mode during transmission, the UH-100 automatically sends the signal at a frequency 30 channels above the original. After transmitting, the radio reverts back to its original operating frequency.

For example,

CHOI on Duplex Mode will Receive on CH 01 but Transmit on CH31 CH02 on Duplex Mode will Receive on CH 02 but Transmit on CH32 etc,,..

If you transmit on CHOI Duplex mode, you are actually transmitting on CH31, the

repeater station down-converts your signal and retransmits on CHOI.

To operate UH-100 in Duplex Mode,

eg. CH01 is being used in your area for

repeater use.

Press DUPLEX momentarily.

The DUP icon appears.

Whenever you press the PTT Switch the UH-100 frequency display changes to CH31 frequency.

Press DUPLEX again to deactivate the Duplex Operation. UH-100 will return to Simplex operation.

Scanning

The UH-100 has a scanning feature that allows you to search for active channels automatically.

Furthermore, the UH-100 is designed to have two types of scanning; Open Scanning (OS) and Group Scanning (GS), to give you flexibility and allow you to use the radio more effectively.

To initiate scanning.

1. Assuming the unit is on CHI 7 when switched on.

2. Press SCN and Scanning starts.

1. Open Scan (OS) Mode

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

Example. CH40 becomes active. If the received signal ceases, the unit will wait for at

least 3 seconds for the signal to return, otherwise

scanning resumes.

To skip the active channel, press MEM momentarily.

Scanning resumes.

To deactivate SCAN, press the SCN switch or the PTT Button.

Note: If SCAN is deactivated white in an active channel, the UH-100 will stay on

that active channel. If no other channels are active, the UH-100 will reinstate the starting channel.

2. Group Scan (GS) Mode

Allows you to monitor a Priority Channel while scanning. To use GS Mode Scanning, press the OS / GS key,

GS icon appears on the display. OS Mode is indicated by the absence of the GS icon.

GS Scanning checks the Priority channel activity regularly.

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, UH-100 will continue monitoring the Priority Channel for activity while listening to the active one.

eg. CH40 becomes active.

To deactivate SCAN, press the SCN key or the PIT Switch.

Note: //SCAN is deaci/Vafed whi/e it is tuned at an active channel, the UH-lOO will

stay on that active channel. If none of the channels are active, the UH-100 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.

Choosing a Priority Channel

The starting channel, when Group Scanning is initiated, is always the Priority Channel. Changing the PRI channel setting while scanning, eg. PRI Channel is CH17 (476.825 MHz)

a, press A , to select a higher channel {scanning pauses)

- or -

b. press ▼ , to select a lower channel

Drop-Out Delay

While scanning, the UH-100 stops at a busy channel and receives a transmission. When the received signal is over, the unit will wait for three seconds for the return of the signal, othenwise, the radio resumes scanning.
