BASIC OPERATION

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 “

21

SUB DIAL” (p.61), must be set to “FrEq.”

qPush [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.

wRotate [M-CH] to change the operating frequency

according to the set tuning step.

ePush [RIT/SUB] again to turn the function OFF.

• The [SUB] indicator turns off.
