Press the switch and the trasmitter is activated, release switch to receive. When
transmitting, hold the microphone 0 cm from the mouth and speak clearly in a normal
‘’voice’’. The radios come complete with low-impedance (500 ohm) dynamic microphone.
For installation instructions on other microphones, see the paragraph ‘’ALTERNATE
MICROPHONES AND INSTALLATION”.
OPERATING PROCEDURE TO RECEIVE

connectors before going to the next step.
2. Turn the unit on by tuning the VOL control clockwise on your transceiver.
3. Set the VOLUME for a comfortable listening level.

quiet until a signal is actually received. Do not advance the control too far, or some of
the weaker signals will not be heard.
6. Set the CHANNEL switch to the desired channel.
7. Set the RF gain control fully clockwise for maximum RF gain.
8. Adjust the CLARIFIER control to clarify the SSB signals or to optimize AM/FM signals.
