Operating Mode Selection; Attenuator Function - Icom IC-80AD Instruction Manual

Operating mode selection

Operating modes are determined by the modulation of the
radio signals. The transceiver has total 5 operating modes
(FM, FM-N, WFM, AM and DV modes). The mode selection is
stored independently for each band and memory channel.
Typically, AM mode is used for the AM broadcast stations
(0.495–1.620 MHz) and air band (118–136.995 MHz), and
WFM is used for FM broadcast stations (76–107.9 MHz).
WFM mode cannot be selected above 810 MHz for U.S.A. ver-
sion.
Push and hold [MODE](BAND) for 1 sec. several times to
select the desired operating mode.
• While pushing and holding [MODE](BAND), rotate [DIAL] is also
available to select operating mode.
