OPERATING PROCEDURE TO RECEIVE
1. Be sure that the power source, antenna and microphone are connected to the proper
connectors before going to the next steps.
2. Turn the unit ON by rotating the OFF/VOLUME Control clockwise.
3. Set the CHANNELSELECTOR switch to the desired channel.
4. Set the OFF/VOLUME Control to a comfortable listening level.
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 re-
main quiet until a signal is actually received. Do not advance the control too far, or
some of the weaker signals will not be heard.
OPERATING PROCEDURE TO TRANSMIT
CAUTION
-
The transceiver Voltage Standing Wave Ratio (V.S.W.A.) measurement must be
performed priorto the use of the transmitter. A V.S.W.R. ratio in excess of 2:1 may
damage the transmitter.
1. Be sure the operator has read and understands D.G.C. Rules and Regulations priorto
operating the transmitter.
2. Select the desired channel.
3. If the channel is clear, depress the PRESS- TO-TALK switch on the microphone and
speak in a normal voice.
PREVENTIVE MAINTENANCE
At six to twelve month intervals, the following system checks should be made:
1. Check Standing Wave Ratio (SWR).
2. Inspect all electrical connections to ensure that they are tight.
3. Inspect antenna coaxial cable for wear or breaks on shielding.
4. Inspect all screws and other mounting hardware for tightness.
