21. DISPLAY FREQUENCY METER. It shows the operating frequency and the selected
channel.
22. INDICATOR. This meter indicates the received signal strength, the SWR level, the
transmitter RF output power, the TX modulation percentage; furthermore it allows the
SWR-meter tuning.
REAR PANEL
23. POWER SUPPLY. Accepts 13.8. VDC power cable with built-in fuse to be connected.
24. EXT SP. Accepts 4 to 8. ohm, 5 watt external speaker to be connected. When external
speaker is connected to this jack, the built-in speaker is automatically disconnected.
25. ANTENNA. Accepts 50 ohm coaxial cable with a PL-259 type plug to be connected.
PRESS-TO-TALK MICROPHONE
The receiver and trasmitter are controlled by the press-to-talk switch on the microphone.
Press the switch and the trasmitter is activated, release switch to receive. When
transmitting, hold the microphone 10 cm from the mouth and speak clearly in a normal
''voice''. The radios come complete with low-impedance (500 ohm) dynamic microphone.
OPERATING PROCEDURE TO RECEIVE
1. Be sure that power source, microphone and antenna are connected to the proper
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.
4. Set MODE switch (11) to the desired mode.
5. Listen to the background noise from the speaker. Turn the SQUELCH control slowly
clockwise until the noise just disappears (no signal should be present). Leave the
control at this setting. The SQUELCH is now properly adjusted. The receiver will remain
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.
