6 SCAN

PROGRAM SCAN

The Program Scan function scans the range between

the lower limit frequency and upper limit frequency

stored in memory channel 99. Scan always begins

scanning upwards in frequency but can be reversed

by turning the Main or the Alternate Tuning control,

or by pressing microphone [UP]/[DWN]. Turning

either control counterclockwise causes Scan to move

downwards in frequency while turning either control

clockwise causes Scan to move upwards in

frequency. Similarly, pressing microphone [UP] or

[DWN] causes Scan to move in the same direction as

the button labels. Menu B, No. 56 must be OFF if the

controls are to function in this manner.

For a refresher on how to store the Scan Limits, refer

to "SCAN FREQUENCY LIMITS STORAGE"

{page 25}.

Program Scan can be broken down into 3 kinds of

scan method.

Type of

Frogram Sean

Purpose

Basic Scan General update of activity on a selected

portion of the band. This is a sub-set of all

frequencies tuned during Band Scan.

Band Scan

Monitor all frequencies tuned by the

transceiver.

MHz Scan

Monitor any single 1 MHz range of

frequencies.

CONFIRMING LOWER/UPPER FREQUENCY

LIMITS

The lower and upper Scan frequency limits stored in

memory channel 99 can be confirmed with the

following procedure:

5 Press [SCAN], [CLR], or microphone [PTT] to

stop scanning and restore VFO mode.

Note: The modulation mode can be changed while scanning.

BAND SCAN

If the lower limit frequency and upper limit frequency

have not been stored in memory channel 99, or if the

current VFO frequency is outside the range bracketed

by the Scan Limits in memory channel 99, the

transceiver scans the entire band.

Press [A/B] to select VFO mode.

Press [SCAN].

• The transceiver scans upwards from the current

operating frequency.

• To change the scan direction, use the
