6 SCANS

DPriority scan

Priority scan monitors a specified frequency (the pri- ority channel) once every 1–16 sec. (programmable) during any operation, such as receiving, scanning other channels, etc.

Start/stop:

Push [PRIO] to start/stop the scan.

•Priority scan can be used in combination with other scan types: start another scan type during priority scan; or, push [PRIO] while operating another scan.

Preparation—priority channel programming: ➀Push [PRIO] for 1 sec.

•“*SET*” appears in the bank name area, then changes to a flashing “PRIO.”

• Using this method, the priority channel can be called up at any time with one push.

➁Set the desired frequency, mode and memory

name.

➃Push [PRIO] again to return to the previous chan- nel.

■Mode select function

To operate memory scan or memory select scan in a specific mode (ignoring other modes), the mode select function is available.

➀Push [MEMO] or [SEL] to start memory scan or memory select scan, respectively.

➁Select the desired mode to operate the scan in via the mode switches.

•The mode select function is applied to memory or mem- ory select scan.

➂Push [MEMO] or [SEL] again to stop the scan.
