OPERATION Operating Procedure to Receive 1. Be sure that the power source, antenna and microphone are properly connected. 2. Turn the unit on by rotating the volume control clockwise. 3. Set the channel selector switch to the desired channel. 4. Set the volume control to a comfortable listening level. 5. Listen to the background noise from the speaker. Turn the squelch control clockwise until the noise disappears (no signal should be present). Leave the control at this setting. The squelch is now properly set. The receiver will remain quiet until a signal is actually received. Do not advance the control too far, or some weaker signals will not be heard. Operating Procedure to Transmit 1. Be sure the operator has read and understands part 95, FCC rules and regulations prior to operating the transmitter. 2. Select the desired channel for transmission. 3. If the channel is clear, depress the push-to-talk switch on the side of the microphone and speak in a normal voice. CAUTION: The transceiver Voltage Standing Wave Ratio (VSWR) measurement must be performed prior to the use of the transmitter. A VSWR in excess of 2:1 may damage the transmitter. Please check your SWR reading frequently by using an SWR meter. Preventative Maintenance At six to twelve month intervals, the following system checks should be made: 1. Check the Voltage Standing Wave Ratio (VSWR). 2. Inspect all electrical connections. 3. Inspect antenna coaxial cable for wear. 4. Inspect all screws and other mounting hardware.
