CONTROLS AND THEIR FUNCTIONS
1. OFF/ON VOLUME: To turn the transceiver on, rotate this control clockwise
past click. To turn the transceiver off, rotate the control counterclockwise past
click. Rotate the control clockwise for a comfortable audio level.
2. SQUELCH: The Squelch control is normally set to a position which eliminates
undesired background noise with no signal present. With the audio adjusted to a
satisfactory level, rotate the Squelch control clockwise to the point where the
sound from the speaker is cut off. In this position, there will be no sound from
the speaker until a signal is received. In order to hear weak signals, it may be
necessary to rotate the Squelch control counterclockwise, allowing some back
ground noise to be heard.
3.
PA SWITCH {on SQUELCH control); Full counterclockwise rotation of the
squelch control engages the PA function. The PA function should not be used
unless an external speaker is connected. In the squelch (or CB) position, the PA
function is disabled and the radio will transmit and receive on the selected
channel.
4. MODE SELECTOR: This switch selects AM, USB, or LSB mode of operation.
This selector changes the mode of operation of both transmitter and receiver
simultaneously. Set the selector to the mode on which you wish to com
municate.
