NOTE: Proximity sensor
When receiving and making calls, the
proximity sensor automatically turns
the backlight off and locks the touch
keypad by sensing when the phone is
near your ear. This extends battery life
and prevents the touch keypad from
activating unintentionally during calls.
WARNING
Placing a heavy object on the phone
or sitting on it can damage its LCD
and touch screen functions. Do
not cover the protective fi lm on the
LCD's proximity sensor. This may
cause the sensor to malfunction.
