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].
([MENU] > SET > Function > Monitor)
■ 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.
L Information
• Options: “OPEN,” “AUTO” (default), and “LEVEL 1” ~
“LEVEL 9.”
• “LEVEL 1” is loose squelch (for weak signals) and
“LEVEL 9” is a tight squelch (for strong signals).
• “AUTO” is an automatic level adjustment using a noise pulse
counting system.
• “OPEN” is the continuously open setting.
• In the DV mode, you cannot set the squelch to “OPEN.”
