BASIC MANUAL

Monitor function
The Monitor function is used to listen to weak signals
without changing the squelch setting.
While holding down [SQL], you can hear weak signals on
the frequency.
TIP:
You can set the Monitor Hold function on the MENU
screen. The transceiver opens or closes the squelch
each time you push [SQL].

Setting a squelch level
Noise squelch enables the audio to be heard only while
receiving stronger signal than the set level. A higher level
blocks weak signals, and receives only stronger signals. A
lower level receives weaker signals.
L
Throughout this document, “Noise squelch” is called
“Squelch.”
While holding down [SQL], rotate [DIAL] to select the
squelch level.
