HT544

Using Your HT544

1. Turn the transceiver on by rotating the volume control in a clockwise direction. A power on tone

is generated after 1 second to indicate the transceiver has passed its self-diagnostic test. During

standby the LED indicator will pulse amber every 3 seconds, to further verify its

circuitry is functioning correctly. Select the desired audio level by further rotating the control

clockwise. After power-on, the transceiver will always default to the last channel selected.

2. Turn the squelch control fully counter clockwise, then rotate clockwise until the white noise stops.

This condition is known as the "squelch threshold". If the control is turned clockwise past this

point, weak signals may not be received. No noise or signal is heard until a signal is received that

exceeds the squelch threshold.

3. Select the desired channel using the [UP/DOWN] buttons. A full listing of channels can be found

on page 17-18. Sometimes, a slight adjustment of the squelch threshold is needed as some

channels have a higher noise level than others.

4. When receiving a signal the LED indicator illuminates green. An “RX” is also displayed on the

LCD.

Reception

Transmitting

1. Perform steps 1 through 3 of RECEPTION.

2. Before transmitting, monitor the channel and make sure it is clear.

3. For communications over short distances, press the [H/L] key and select low power (1 watt).

Transmitting on 1 watt prolongs battery life, and should be selected whenever possible.

4. When receiving a signal, wait until the signal stops before transmitting. The transceiver cannot

transmit and receive simultaneously.

5. Press the [PTT] (Push-To-Talk) button to begin your transmission. To confirm transmission in

progress the LCD indicator illuminates TX and the LED illuminates RED.

6. Hold the transceiver 1 inch from your mouth and speak slowly and clearly into the microphone.

7. When the transmission is finished release the [PTT] button.

Turning The Radio On & Off

Turn the ON/OFF control on the top of the radio clockwise until the LCD iluminates & a short

beep is emitted. To turn the radio off turn the ON/OFF control anti-clock wise until the LCD

deluminates.

Using Your radio

Before using your radio you may need to adjust the volume on the radio to take in to account

background noise. Adjust the volume using the rotary control on the top of the radio.
