4-5. SC FREQUENCY SCANNING.
The RT can scan up to eight preset SC frequencies. The frequencies it can scan are the ones loaded into the pre-
sets 1-6, MAN, and CUE. When a signal is found, that channel is locked in. The RT display will show the channel
number, and you can listen and talk on that channel. When the channel has been inactive for 2.5 seconds, scan-
ning will begin again.
One of the presets can be selected to be the priority preset. The priority preset is scanned more often. The RT
will transmit on the priority preset at any time just by pressing the push-to-talk on the headset.
(1). Set RT switches: FUNCTION - SQ ON; MODE - FH; PRESET - CUE. Set other switches as needed.
(2). Press STO (Sto/ENT) button on RT. The display reads SCAN_.
(3). Press a number, 0-8. This tells the RT which preset has priority (0 is MAN; 7 is CUE; 8 is no priority).
