tone squelch manually.

■ 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. TV and ATV (ATV type only) also use WFM
mode. The mode selection is stored independently 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).
➥ Push [MODE] one or more times to select the desired re-
ceive mode.
