channel is found, the radio will switch to the new system and sound an alert tone. Group selection may change upon switching to the new system.

The radio may also be programmed for priority wide area system scan. A priority system may be assigned to each system programmed into the radio. Radios programmed in this manner will scan the priority trunked system’s control channel once every one, two, three or four minutes (programmable). This priority scan timer is reset each time the PTT bar is pressed.

ProSound™

The radio may be programmed for ProSound system scan operation for multi-site applications. ProSound scanning is an enhanced replacement for wide area system scanning. This algorithm insures that the radio continu- ally receives high quality audio. When the selected system degrades to a preprogrammed level, the radio begins searching for the best adjacent system on a part time basis. Once a better system is found the radio changes to the new system and sounds a tone. Should the control channel be lost completely, the radio will scan the adjacent systems until a suitable one is found.

DYNAMIC REGROUPING (Optional)

Dynamic Regrouping is a feature which allows the System Manager to dynamically program new groups into selected radios. Upon development of the regrouping plan, the site controller sends each radio the regroup plan number, "group position", and activate/deactivate commands. When the radio is regrouped, it will alert the user and the Group field will will display the regroup number "nn" (nn = 01-08).

NOTE

The regroup is identified by the leading zero in the 10’s digit of the Group field. This zero is normally surpressed in Groups 1-8.

DTMF OVERDIAL

After the radio has acquired a working channel to make a message trunked call, DTMF tones can be sent by:

1.Pressing and holding the PTT bar.
