Motorola GP68 operation manual Redial, Priority Call Override

1 • Operation

1.4.4Redial

Redial is most often used after a telephone number is dialed using the store and send method and the line is busy or a trunking channel is not available.

Example: To redial the last number dialed:

Press the * key twice.

Turning off the power to the radio clears the redial memory. If redial is attempted when no number has been entered, a low frequency error tone will be heard. Redial may be re- peated as many times as desired.

1.4.5Priority Call Override

A subscriber unit programmed as a priority subscriber can initiate a Priority Call Override after a call is attempted but all channels are busy. Priority Call Override will try to pre-empt an ongoing call.

If a channel is not available for a call, Priority Call Override can be used to try to gain access to a channel.

To start a Priority Call Override:

Press and release the * key, and then

press and hold the * key until a beep is heard.

Each subscriber is assigned one of ten priority levels. When the ST-852M receives a priority call override command, it compares the priority level of the current call in process with the override command. If the override command is a higher priority it will pre-empt the call in process. Once the trunking channel is released, the priority subscriber’s call will be pro- cessed in the normal fashion. If a channel is not made avail- able, a busy signal will be heard by the subscriber.

Programming a subscriber unit as a priority subscriber does not guarantee access to the system. A priority subscriber may be denied access depending on the priority level of the other subscribers. Access may be impossible if the RF sig- nal strength of the current subscriber on the trunking chan- nel is stronger than that of the priority subscriber. Priority Call Override is a dealer programmable option.
