• Sub dial function
The sub dial function allows you to change the oper-
ating frequency using the [M-CH] control. This gives
you more control in tuning since the [M-CH] knob is
detented—each click changes the frequency accord-
ing to the set tuning step. This function is always
available in FM and AM modes. However, in SSB,
CW and RTTY modes, the initial set mode item "
" (p.61), must be set to "FrEq."
q Push [RIT/SUB] to turn the sub dial function ON.
• The [SUB] indicator lights green; if it lights red, the RIT
function is activated—sub dial function must be set in
initial set mode in this case.
w Rotate [M-CH] to change the operating frequency
according to the set tuning step.
e Push [RIT/SUB] again to turn the function OFF.
• The [SUB] indicator turns off.
