Weather Alert Scan - Yaesu FT-252 Operating Manual

Scanning
This feature allows you to check the Weather Broadcast Memory Channels for the pres-

Broadcast Memory Channels for activity every five seconds while scanning. If you

Tone, after which regular scanning will resume for another five seconds.

period of monitoring time, as no power will be consumed via audio output while
scanning for the Alert Tone is in progress.
