a continuously open setting and an automatic squelch setting.

While pushing and holding [SQL], rotate [DIAL] to select
the squelch level.
• “LEVEL 1” is loose squelch and “LEVEL 9” is tight squelch.
• “AUTO” indicates automatic level adjustment with a noise pulse
count system.

Receive mode selection
Receive modes are determined by the physical properties of
the radio signals. The receiver has 3 receive modes: FM, AM
and WFM modes. The mode selection is stored indepen-
dently in each band and memory channels.
Typically, AM mode is used for the AM broadcast stations
(0.495–1.620 MHz) and air band (118–135.995 MHz), and
WFM is used for FM broadcast stations (76–107.9 MHz).
