“OFF” is underscored: scan pauses on a signal until it disappears, then resumes 3 sec. after that.

“DLY” is underscored: scan resumes according to the

[DELAY/SPEED] control setting. When a signal dis-

” is underscored: scan is cancelled when receiving a signal.

Push for 1 sec. to enter the delay time/scan speed setting condition.
