1.13 Frequency Scan

Channel scan

Scan is the function where the receiver watches 10/group user or ITU channels in succession at

predetermined intervals. The scan-stop signal level and scan-stop time can be changed on sys-

tem codes 9951 and 9952, respectively. AGC is automatically turned on when scanning is acti-

vated.

1. Recall user or ITU channel.

User channels

User channels are divided into 20 groups in the scan mode as below.
