Keypads
The MC55 offers three types of keypad configurations: Numeric, alpha-numeric and PIM.
Numeric Keypad Configuration
The numeric keypad contains application keys, scroll keys, and function keys. The keypad is color-coded to
indicate the alternate function key (blue) values. Note that an application can change keypad functions so the
MC55’s keypad may not function exactly as described. See Table 2-8 for key and button descriptions and Table 2-9
on page 2-21 for the keypad’s special functions.
