Never operate the transceiver without an antenna connected.
Before proceeding, please read the Controls and Connectors chapter if you have not al-

Connect the antenna to the top panel ANTENNA
jack.

Switch on the transceiver by rotating the VOL con-
trol clockwise out of the click-stop (a momentary
beep will sound).
If you don't hear the two "Beep" tones when the radio comes on, the Beeper may have
been disabled via the Menu system. See page ??, which tells you how to reactivate the
Beeper.
Rotate the VOL control (immediately to the right of the Antenna) to set the desired audio
level. Clockwise rotation increases the volume level.
Set the SQL control fully counterclockwise, rotate the
VOL control out of the click-stop and adjust for a com-
fortable volume on the noise or received signal. The
BUSY/TX indicator LED should glow green. If a sig-
nal 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 extin-
guished. If the SQL control is set further clockwise, sensitivity 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.
