Using the Rotary Dial

You can select a higher or lower fre- quency by turning the ROTARY TUNING knob up or down.

Set FAST/FINE/LOCK to select the rota- ry tuning increments or to lock the RO- TARY TUNING dial. If you select FAST, the rotary tuning increments are the same as when you use the MANUAL/

AUTO or keys. If you select FINE, the tuning increments are small-

er so you can fine tune the frequency, as shown in the following table.

You can also set FAST/FINE/LOCK to lock the ROTARY TUNING dial. This prevents you from accidentally chang- ing the frequency.

Note: This locks only the ROTARY TUNING dial. For information about locking the front-panel buttons, see “Locking the Controls” on Page 22.
