Receiving

q Push [PWR] to turn the power ON.
w Push [SQL], then turn the [DIAL] counterclockwise (or [Z]
key) to select the squelch level [0].
e Push [Y]/[Z] key several times to adjust the audio level.
r Push [SQL], then turn the [DIAL] clockwise (or [Y] key)
until the noise is muted.

t Set the desired frequency using the [DIAL] or keypad.
y Push [ANL] to reduce pulse noise such as that caused by
engine ignition systems, if necessary.

"loose" position.

Transmitting

CAUTION: Transmitting without an antenna may damage
the transceiver.
NOTE: To prevent interference, listen on the frequency be-
fore transmitting. If the frequency is busy, wait until the
channel is clear.

or keypad.
• COM band frequency range: 118.00–136.975 MHz
w Push and hold [PTT] to transmit.
• The Tx/Rx indicator lights red.
