When FINE TUNING is activated, the
amount of frequency change of the Main dial
does not become a higher step rate.

knob. When "Lock" is ON, the MAIN Dial knob can
still be turned, but the frequency will not change,
and "MAIN LOCK" appears in the frequency dis-

FINE TUNING (Tuning of 1 Hz)
In the SSB, CW, RTTY, DATA-L or DATA-U mode,
the frequency can be adjusted in 1 Hz steps.
● The AM, FM, DATA-FM modes may be adjusted
in 10 Hz steps.
1. Press the [FINE TUNING] key.
2. Rotate the MAIN dial knob.
While FINE TUNING is operating, the MAIN
dial frequency change will not be 10 times
faster, even if the FAST function is activated.
