1.4.4 Redial
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.
1.4.5 Priority 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.
