Introduction
Your MIT message pager is an alphanumeric
pager which is able to receive text messages
and store them for you to view later. The high
contrast screen is capable of displaying up to
96 characters, while all operating functions may
be performed by intuitive menus using just 3
high tactile buttons. An additional feature is
that no pictograms or icons are used on the
screen. You do not have to remember the
meaning of special symbols as all status
messages and operating prompts are displayed
in plain language messages.

Status and warning messages
When your MIT message pager is switched on
but is not displaying a message or menu, the
standby screen is displayed. This always
consists of the time and date but additional
status and warning messages may also be
displayed. A typical screen is shown below
with some of the status and warning messages
that you may see.
The first line always acts as a clock showing
the current time and date. The current date is
shown in the centre of the first line. You may
set the time, selecting either 12 or 24 hour
mode and set the date.
The right side of the top line may show Alarm
to denote that the internal alarm is currently
set. When displaying messages from memory,
the message status is shown here; either
Unread, Read or Archiv.

The second line displays No Unread
Messages or 1 Unread Message to show how
many messages have been received but not
viewed. Sometimes, another message,
Memory Full may alternate with the message
status. This means that the memory is almost
full and the next message may overwrite the
oldest read message.
The third line shows the status of the alert;
Silent to warn that the audible alert has been
turned off or No Vibrate to show that the
vibrate alert has been turned off. When both
audible and vibrate alerts are turned off, Silent
and No Vibrate alternate at 2 second intervals.
If nothing is displayed, both audible and vibrate
alert are turned on.
The bottom line may display Replace Battery
to indicate that the battery is low and should be
changed as soon as possible. Radio Off may
also be displayed on the bottom line. This is a
special battery saving feature. Some MITs are
programmed to display Out Of Range on the
bottom line when they are out of range of a
transmitter.
Switching Off Your MIT Message Pager
When the standby screen is displayed, press
and release the > button. The options screen
will now be displayed.
The two pointers show the item that will be
selected if the > button is pressed. If you do
not press any button within 16 seconds, your
MIT will revert back to the standby screen. Use
the up or down buttons to move the pointers to
Off. Select by pressing the > button. The
pointers will change to question marks showing
that confirmation is required to switch off.
Press the > button again and your MIT will
switch off. If switch off is not required, press
either the up or down button. When your MIT
is switched off, any messages you have
received will be retained in memory and the
