4-3. TRANSMITTER OPERATION
Cautions: -
1. Ensure that an antenna with a low standing wave ratio
(SWR)} is attached to the antenna connector before at-
tempting to transmit. Failure to provide proper termina-
tion may result in damage to the final amplifier section.
2. Always check to ensure the frequency is clear before
transmitting.
Note: me wae ee
The use of LOW power is recommended, whenever possi-
ble, to avoid interfering with other stations.
4-3-1. Transmit Basics
1. Select the desired operating frequency using any of the
methods previously discussed.
2. Check the frequency to see if it is occupied before you
transmit.
3. Press the PTT switch. The ON AIR indicator wilt light,
and the RE meter will deflect to the right.
Note: —.
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 swing full scale.
4. Speak into the microphone. The he recommended distance
to the microphone is 5 cm (2 inches).

Note: cece eee weeeeee eee —
Talking closer may result in overdeviation of your trans-
mit signal, which might be reported as a loss of clarity
or of an excessively wide transmit signal. Talking too far
away may. result in reports of weak audio.
. Release the PTT switch to return to the receive mode.
The ON AIR indicator should go out, and the RF meter
will return to zero.
™~ 4-3-2. Duplex Operation
Pressing the PTT switch on the microphone aliows simul-
taneous receive on 8 UHF (or HF) and transmit on the other
band. —__

. Select the desired VHF transmitter frequency.
2. Prese the BAND key and select the-desired UHF receive
frequency.
Press the F key momentarily, and then press the
BAND/OUP key. The D indicator will turn on in the dis-
play to remind you thet duplex operation has been ac-
