Description of alarm operation
Triggering a message
Bit 1 of alarm register one is assigned message #34, which reads This is a test
message.
Bit 5 of alarm register one is assigned message #35, which reads The phone is
ringing.
Bit 2 of alarm register two is assigned message #36, which reads An alarm
message.
Bit 2 of register two goes to the ON state. The display shows message 36:
AN ALARM MESSAGE.
Then bit 1 of alarm register one goes to the ON state. The display shows message
34:
THIS IS A TEST MESSAGE.
Finally, bit 5 of alarm register one changes to the ON state. The display shows message 34:
THIS IS A TEST MESSAGE.
Note how the first alarm encountered inhibits the message from bits 5 of reg. 1 and 2 of reg. 2 from
being displayed. Actually, they are never processed.
Bit 0 of register one goes to the ON state. Since no message is assigned to that bit the display shows
the message that is in the Message Triggering Register or the default message.
3.3 Using the Function Keys
The MMI-100, 110 and 140 models have programmable function keys. Simply press a Function key
to initiate their programmed action and/or call up their associated messages. One of the following
conditions will apply.
3.3.1 The Function key may have message text assigned to it or may be chained to
a message.
The Function key message will interrupt the active display.
Note: Function keys with message text assigned to them clear the message
Queue and interrupt minimum display times, chained and scrolling messages.
The message assigned to the Function key will be displayed.
At the end of a Function call and after all message chaining is done, the display does one of the 3
options listed in priority below.
1 Chains, if programmed, to the next message.
2 Displays the message whose number is next in the message Queue.
3 Displays the message whose number is in the MTR.
3.3.2 No message text is assigned to the Function key and no messages are
chained to or from the Function key.
Press the Function key. The Queue is not cleared and the display is not be interrupted but the
