OPERATION INSTRUCTIONS
Having properly installed your batteries and hooked-up the antenna, you are now ready to operate your
radio for optimum reception and voice transmission.
Turn the power “ON” with ON/OFF switch.
Set the desired channel.
Adjust the squelch control knob to reduce any undesirable background noise when no signal is being
received. To do this, select a channel where no signal are present, or wait until signals cease on your
channel. Then, rotate the squelch control knob clockwise to a point where the background noise
disappears.
Note: When the squelch is set properly, the speaker will remain quiet until a signal is
received. In order to receive weak signals, do not set the squelch too high.
Adjust the volume to the desired listening level.
To Transmit
Press and hold the push-to-talk button. Speak slowly and clearly in a normal voice two to three inches
from the microphone. A buit-in modulation control circuit will automatically adjust the microphone input
level. There is no need to speak loudly.
To Receive
Release the push-to-talk button.
