Digital squelch functions

signal addressed to your own call sign, or a signal that
includes a matching digital code.
You can silently wait for calls from others.
You can independently set the Digital squelch function
in the VFO mode, Memory mode, CALL channel
mode, or DR function.

Pocket beep
When a received signal is addressed to your own call
sign, the beeps sound for 30 seconds and an "S"
blinks. Within 30 seconds, push [PTT] to answer, or
operate the transceiver to stop the beeps and turn
OFF the Pocket beep function.
• "S" disappears.
L If you make no operation for 30 seconds, the beeps
automatically stop, but "S" continues to blink to
indicate that you received a call.
NOTE:
• DO NOT use the digital call sign squelch function
when communicating with two or more stations,
because the digital call sign squelch function
opens only when receiving a signal addressed
to your own call sign. Thus the digital call sign
squelch function can be used when communicating
with only one station.
• Even if the squelch closes by the digital call sign
squelch function, you can receive data in the DV
mode.
