■ Operating mode selection

Operating modes are determined by the modulation of the
radio signals. The transceiver has 3 operating 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).
WFM mode cannot be selected below 30 MHz bands.
