BASIC OPERATION
Receiving
■
q
Push [PWR] for 2 seconds to turn the power ON.
w
Push [SQL•
WX-ALERT
], then rotate [DIAL] counterclock-
wise to select the squelch level 0.
e
Rotate [VOL] to adjust the audio level.
r
Push [SQL•
WX-ALERT
], then rotate [DIAL] clockwise until
the noise is muted.
• “
” indicator disappears.
t
Set the desired frequency using [DIAL] or keypad.
y
When a signal is received on the set frequency:
• “
” indicator appears.
• Squelch opens and audio is emitted from the speaker.
When [SQL] setting is too “tight,” squelch may not open for
weak signals. To receive weaker signals, loosen the squelch.
ANL function
■
While receiving, the ANL (Automatic Noise Limiter) function
reduces noise components such as those that are caused
by engine ignition systems while receiving.
• Push [ANL•
SCAN
] to turn the ANL function ON/OFF.
“

kHz, the optional CS-A24 (#02)
cloning
software
and the
optional cloning cable are required.
See “Cloning using PC” (p. 25) for details.
Setting a squelch level
■
The transceiver has a noise squelch circuit to mute unde-
sired noise while receiving no signal.
q
Push [SQL•
WX-ALERT
], then rotate [DIAL] to select the
squelch level.

• COM band frequency range: 118.000–136.9917 MHz
w
Hold down [PTT] to transmit.
• “
” indicator appears.
e
Speak into the microphone at a normal voice level.
•
DO NOT hold the transceiver too close to your mouth or speak
too loudly. This may distort the signal.
