Saved Alarm messages:

Press the DISPLAY button for five seconds and then release to display
the first Saved Alarm message in the message queue.
2. Press and then immediately release the DISPLAY button to display
each additional message.
The display defaults back to the product name if the DISPLAY button
is not pressed again within ten seconds.
