Rotate the VOL control (immediately to the right of the Antenna) to set the desired audio
level. Clockwise rotation increases the volume level.

ETUP
Set the SQL control fully counterclockwise, rotate the VOL
control out of the click-stop and adjust for a comfortable
volume on the noise or received signal. The
BUSY/TX
indicator LED should glow green. If a signal is present,
rotate the
DIAL selector on the top panel to a channel where
only noise is heard.
Adjust the SQL control just to the point where the noise is
silenced and the LED is extinguished. If the SQL control is set further clockwise, sensi-
tivity to weak signals will be reduced. Now, whenever a signal reaches the receiver that is
strong enough to open the squelch, the indicator will glow green.
T
RANSMITTING
When you wish to transmit, wait until the channel is clear (
BUSY/TX
lamp off), and
squeeze the PTT switch. During transmission the BUSY/TX indicator glows red, and
relative transmitter power output is indicated graphically along the bottom of the display.
Release the
PTT switch to receive.
If using a “B” version (in Europe), press the
T-CALL
switch (just below the
PTT
switch)
to transmit a 1750 Hz tone to access repeat-
ers that require it.
