3 FREQUENCY AND CHANNEL SETTING

DUsing the keypad

The frequency can be directly set via numeral keys.

•When editing a frequency outside of the fre- quency range, the previously displayed frequency is automatically recalled after editing last digit.

Pushing [VFO MHz] omits the entry of 100 kHz and below, when you want to edit to these digits “0.” Push [DUALWATCH] to cancel the entry.

qPush [VFO MHz] to select VFO mode, if necessary.

• Editting to 0.820 MHz • Editting to 1260 MHz • Changing 100 kHz and below.

wEnter the desired frequency via the keypad.

•Direct input can be set until 1 kHz digit, rotate [R-DIAL]to set below 1 kHz frequency after set tuning steps, if necessary. (See the previ- ous page for setting the tuning step.)
