ProSound/ProScan algorithm is enabled as explained on the following page). This priority scan timer is reset each time the PTT button is pressed or when the call is received. If the priority system control channel is found, (or meets the predefined criteria (ProSound/ProScan)), the radio will automatically switch to the priority system.
When Wide Area System Scan Is Enabled:
If the radio cannot find the control channel of the selected system and begins to wide area system scan, the radio will only scan for the priority system control channel if the priority system is in the wide area scan list.
When ProSound/ProScan Is Enabled:
The radio monitors the priority system and will switch to the priority system if the criteria defined by the controls in the ProSound/ProScan Options dialog box are met. If ProSound/ProScan is enabled, the rate at which the radio will scan for the priority system is defined by the System Sample Time control, located in the ProSound/ProScan Options Dialog box.
