Receiving and transmitting

■
Receiving:
Rotate [VOL] to turn ON the power.
q
Rotate [ROTARY SELECTOR], or push one of the memory
w
channel keys, [MR-CH 1] to [MR-CH 4], to select a channel.
When receiving a call, adjust the audio output to a comfortable
e
listening level.
• When the received signal contains the same CTCSS tone or DTCS
code, the LED indicator lights green.
• If no audio is heard, hold down [MONI] while adjusting the audio
output level. Release to receive.
The transceiver is now set to receive on the selected channel.
r
NOTE: The transceiver may be equipped with CTCSS tone or
DTCS code capability. The CTCSS tone squelch or DTCS
squelch opens only when the received signal includes a match-
ing tone or code. You can silently wait to receive calls from only
stations using the same tone or code. The default settings for
each channel are listed on the next page.
Transmitting:
Wait for the channel to become clear to avoid interfering.
While holding down [PTT], speak into the microphone at a nor-
q
mal voice level.
Release [PTT] to receive.
w
IMPORTANT: To maximize the readability of your signal;
1. Pause briefly after pushing [PTT].
2. Hold the microphone 5 to 10 cm from your mouth, then speak
into the microphone at a normal voice level.
