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.
“ ” appears on the display while the ANL function is ON.
Channel spacing setting
■
If you set the channel spacing to only 8.33 kHz or only 25
kHz, the optional CS-A24 (#02) c l o n i n g s o f t w a r e 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.
• ‘SQL--0’ is open squelch and ‘SQL--24’ is tight squelch.
• “ ” appears while the squelch is open.
w Push [SQL•WX-ALERT] or [CLR•DEL] to exit the squelch
set mode.
Transmitting
■
q Set the desired frequency in COM band using [DIAL] or
keypad.
• 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.
r Release [PTT] to return to receive.
CAUTION: Transmitting without an antenna may damage
the transceiver.
NOTE: To prevent interference, listen on the frequency
before transmitting. If the frequency is busy, wait until the
channel is clear.
