5-3 TRANSMITTER OPERATION

Caution

1. Ensure that an antenna with a low standing wave

ratio (SWR) is attached to the antenna connector

before attempting to transmit. Failure to provide

proper termination may result in damage to the

final amplifier section.

2. Always check to ensure the frequency is clear

before transmitting.

Note

The use of LOW power is recommended whenever

possible, to avoid interfering with other stations.

5-3-1 Transmit Basics

1. Select the desired operating frequency using any of

the methods previously discussed.

2. Press the LOW/DIM key to select the desired transmit

output.

3. Check the frequency to see if it is occupied before

you transmit.

4. Press the PTT switch. The ON AIR indicator will light,

and the RF meter will deflect to the right.

If you have selected the LOW power position, the low

indicator will appear in the display and the RF meter

will only deflect slightly. When HI power has been

selected the RF meter will deflect full scale.

5. Speak into the microphone. The recommended

distance to the microphone is 5 cm (2 inches).

5-3-2 Time-out Timer (TOT)

The TOT can limit the continuous transmission time to

30 minutes.

1. Press the F key for longer than 1 second, then press

the LOW/DIM key. The T indicator will light. To cancel

the setting, repeat the operation.

Press the key for longer than

1 second.

2. When the time-out timer reaches the transmission

time limit, a beep will sound and the transceiver will

return to the receive mode. To transmit again,

release the PTT switch and press it again.
