Sub Tuning Dial - Icom IC-820H Instruction Manual

@ Sub tuning dial
The transceiver has a large main tuning dial for
frequency setting. In addition, the [RIT] or [SHIFT]
controls can be used as a sub tuning dial for dual
band simultaneous tuning, etc. The sub tuning dial
changes the operating frequency continuously at a
variable speed.
To use the sub tuning dial function, assign the func-
tion to either the [RIT] or [SHIFT] control using the
L-set mode item 7 as described at right.
% The assigned control can be used for its original
function, however, both functions cannot be used
simultaneously.
