Special Functions

Memo Function
The memo function is a storage function for text messages. All messages received
are stored in the pocket unit's memory. If the memo function is activated, the
pagings in the memory will be kept when the pocket unit is turned off. The mes-
sages are erased manually or automatically according to the FIFO principle (First In
First Out). However, if the battery is removed or completely discharged, the stored
messages will be erased.
Watchdog Function
The transceiver has a so-called watchdog function. It is an internal hardware and
software function check that is executed at fixed time intervals.
INFO Page Message
An INFO-page contains information that is updated frequently, such as measure-
ments in a production process, exchange rates, stock market notations, etc. An
INFO-page can, for example, be sent from a PC via a serial interface. U922 can
receive one info-page per call number i.e. altogether six. When an info-page is
displayed the symbol appears. By selecting the beep code, it is possible to
choose if the transceiver shall beep or not when an info message is received.
Call-Number Presentation
If a paging has been received on one of the
five extra call numbers, U922 can show which
number received the paging. The call number
is shown at the end of the message preceded
by the symbol +. The symbol and number
information are added by the pocket unit.
Call Diversion
A paging can be directed to another pocket
unit via the central unit of the system. This is
indicated in the display by showing the call number
of the pocket unit that the call was directed from at
the end of the message, preceded by the symbol /.
The symbol and number information are added by
the system.
Out of Range
This is a warning function that checks that the pocket unit is within the coverage
area. A special test paging is sent from the central unit at regular intervals. If the
test paging has not been received by the pocket unit within a preset time, the
symbol appears in the window. The function is selected in Pocket Unit Programmer
and the time interval can be set from 5 to 75 minutes.
Error Indication
If the symbol appears in the window, the transceiver may be out of range. If
the symbol does not disappear when the transceiver is brought back into the
coverage area, the transceiver must be sent to the dealer for service.
