BASIC OPERATION
TURNING THE PHONE ON/OFF
To turn on the phone , flip open the cover then press . The
phone performs a short self test and sounds a tone, the key-
pad backlight turns on for about 17 seconds, and
on ap-
pears. The phone is ready to use when NS (no service)
disappears (see “Signal Strength/Service Area”).
Notes:
• The keypad backlight turns on for about 15 seconds
every time you press a key, then it turns off and all but
the green signal strength indicator disappear from the
display to conserve battery power. When the phone is
locked (see “Locking Your Phone” on Page 36), how-
ever, the phone’s display goes completely blank about
15 seconds after you press the last key.
• During battery charging, the keypad backlight does not
turn off and the display does not change or go blank
when the phone is turned on and unlocked.
To turn off the phone , press again. The display goes
blank.
SIGNAL STRENGTH/SERVICE AREA
The phone always displays a green signal strength meter
when it is turned on to indicate the strength of the cellular sig-
nal currently being received. The more bars that appear on
the meter, the stronger the signal.
