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.

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.
