SCANS 6

■Automatic bank limit/skip functions

When starting a scan, the following functions are automatically turned ON by default; and the [SKIP] and [BANK] switches are deactivated during scan.

•The bank limit function (for memory scan and select memory scan)—The memory scan operates within the selected bank only.

• Turning OFF the automatic function

•The skip function (for any scan except priority scan)—memory channels specified as skip chan- nels are not checked during memory scan and select memory scan; the frequencies which are pro- grammed into memory channels as skip channels (not only in the skip bank but any memory chan- nels) during programmed scan and auto memory write scan.

➀Push [MEMO] for 1 sec.

•A display as at right appears.

➁Rotate the [M-CH] selector to select the item, SKIP or

BANK.

➂Rotate the main dial to select the function AUTO or MANU- AL.

➃Push [MEMO] to return to the previous display.

[BANK] does not function during scan.

BANK MANUAL

The bank limit function is turned ON and

■Voice scan control function

This function is useful when you don’t want unmodu- lated signals pausing or cancelling a scan. When activated, the receiver checks received signals for voice components.

If a receiver signal includes voice components, and the tone of the voice components changes within 1 sec., scan pauses (or stops). If the received signal includes no voice components or the tone of the voice components does not change within 1 sec., scan resumes.

To toggle the function ON and OFF, push [VSC].
