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.
