CHAPTER 2
GETTING STARTED — GPS 100 FUNDAMENTALS
The front panel consists of a 3- line, 22- character LCD display and 21 keys.
Both the display and keypad are illuminated for your convenience while
operating in the darkness.
Flashing “M” character for new mes-
sages; steady “M” if messages remain
on the Message page after you view
them.
No “M” character if no messages.
Information displayed on the LCD is commonly referred to as a “page”.
Notice the “M” character in the upper right-hand corner of the display
illustrated above. This symbol is known as the Message Annunciator and will
flash if the GPS 100 wishes to tell you something. The unit also contains an
internal tone generator that will sound with the flashing Message Annunciator
(if your unit is connected to an external alarm system, it will also be activated).
