■Squelch level setting

The squelch circuit mutes the received audio signal depend- ing on the signal strength. The receiver has 9 squelch levels, 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.

•“OPEN” indicates continuously open setting.

■ 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-	4
dently in each band and memory channels.	4

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).

➥Push [MODE•SCAN] several times to select the desired re- ceive mode.
