Priority System Scan
The radio may also be programmed for Priority System Scan. (To ensure that this feature operates correctly, the control channel of the priority system must be located on channel one unless you are using the ProSound / ProScan algorithm). The priority system is the desired or preferred system. While receiving the control channel of the selected system, the radio will periodically leave the selected system and search for the control channel of the priority system at a programmable rate. The programmable rate is defined by the value in the Priority Scan Time control, (unless the ProSound
/ProScan algorithm is enabled as explained below). This priority scan timer is reset each time the PTT button is pressed or when a call is received. If the priority system control channel is found, or meets the predefined ProSound/ProScan criteria, 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 System Scan list.
When ProSound/ProScan Is Enabled
The radio monitors the priority system and will switch to the priority system if the system meets the criteria defined in the ProSound / ProScan Options Dialog Box. 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.
