Priority Channel Sampling

General

The priority channel sampling feature ensures that when standard scanning, messages on the priority channel are not missed while listening to a message on some other channel. Your transceiver can be programmed so that the priority channel is a fixed channel associated with the current scan list, the currently selected channel, or not used. When the selected channel is a priority channel, “P” is indicated in the upper right part of the display.

Priority channel sampling occurs only with Standard conventional scanning. It does not occur with Radio Wide scanning, when listening to any type of SMARTNET/SmartZone call, or when transmitting. A series of “ticks” may be heard when the priority channel is sampled while listening to a message on some other channel.

Changing The Priority Channel

If a specific priority channel is associated with the current scan list, it can be changed if the Priority option switch is programmed. Proceed as follows:

1.Make sure all scanning is off (neither the standard scan “S” icon or

radio-wide scan icon displayed).

2.Select the channel that you want to be the priority channel using the channel selector switch on the top panel. If the channel is in a different zone, also select the appropriate zone.

3.Press the Priority option switch and the “P” icon is displayed to indi- cate that the selected channel is now the priority channel.
