The two way radio Priority Channel Scan feature allows users to prioritize certain channels over others during the scanning operation. This enables a more frequent checking of the preferred channels over other channels and reduces the likelihood of missing important messages or conversations over the preferred channels.
For example, if the radio has 8 set channels, the normal scan operation scans the channels in the following way Ch1 >> Ch2 >> Ch3 >> Ch4 >> Ch5 >> Ch6 >> Ch7 >> Ch8 >> Ch1 >> Ch2 >> Ch3
But, if the user set the priority of Channel 3 as 1, then the scan operation will scan the channels in the following order Ch3 >> Ch1 >> Ch3 >> Ch2 >> Ch3 >> Ch4 >> Ch3 >> Ch5 >> Ch3 >> Ch6 >> Ch3 >> Ch7 >> Ch3 >> Ch8 >> Ch3 >> Ch1
If the user set the priority of Channel 3 as 1, and of Channel 5 as 2 then the scan operation will scan the channels in the following order Ch3 >> Ch1 >> Ch5 >> Ch2 >> Ch3 >> Ch4 >> Ch5 >> Ch3 >> Ch6 >> Ch5 >> Ch7 >> Ch3 >> Ch8 >> Ch5 >> Ch1
If the radio is on a non-priority channel, some models of the two way radio keeping checking for activities on the priority channels and if activity is detected on any of the priority channels, the radio switches on to the priority channels.
