Speaker Control Key
Press to activate the earpiece (low audio) or speaker
(high audio), depending on the menu settings.
Keypad Backlight Sensor
The MTP850 keypad can be illuminated whenever the
display’s backlight is on. The keypad backlight sensor
determines whether there is a need to light up the keypad
backlight, by measuring the ambient light intensity. This is a
way to provide power saving.
When the radio is in the battery charger (including Digital Car
Kit), the keypad backlight shall remain illuminated and the
photo sensor shall be ignored.
Aliases (Names)
Aliases are optional names that you can assign to stored
phone and private numbers (or IDs). To edit an alias, see
page 85.
Aliases can be up to 12 characters in length and may consist
of letters, numbers, and spaces.
Aliases are displayed during contact list scrolling or during an
incoming call. Aliases are also used in alphanumeric search
to retrieve numbers from your memory list.
