2.1.2 KEYPAD
The Keypad has more than one function and many are self-evident, so only the main
key functions are discussed here.
Figure 2-4
The ON-OFF and PROG/EXIT keys are toggles. They are often discussed here by
separate function to avoid confusion.
For example, the ON key and the OFF key are the same key but its function changes
(toggles) between “ON” and “OFF”. All keys but the ON key are disabled when the unit
is “OFF”.
