Keypad Layout
The numeric keypad with the keys 0 to 9, *, and # is used to enter digits
and letters. Depending on the operating mode, different actions can be
performed (see the table below):
• Entry of digits only (e.g., when dialing a phone number)
• Typing in letters and digits by pressing the keys repeatedly
(similar to a cellular phone), etc.
