Proximity sensor
Proximity
Sensor
When receiving and making calls,
this sensor automatically turns
the backlighting off and locks the
touch keypad by sensing objects
when the phone is near the ear. This
makes the battery life last longer
and prevents the touch keypad
from malfunctioning through
automatic key locking during
calls. Users, therefore, do not have
the inconvenience of unlocking
the phone when searching the
phonebook during calls.
Proximity calibration may
be needed in the event of a
malfunction, for example if the
screen turns off when starting to
receive or make a call.
Proximity calibration
When making or receiving a call,
this function resets the distance
measurement performance between
the phone and the ear. Please be
careful not to block the proximity
sensor, including the protective film
and fitting case, during calibration.
From the home screen select
1
then scroll through Phone
settings in the Settings tab.
Touch
2 Proximity calibration and
Start calibration.
WARNING
Do not place anything, such as
protective  lm, leather cases,
hands or foreign bodies over the
proximity sensor, or expose the
proximity sensor to moisture,
at any time, including during
calibration.
A malfunction (i.e. a black screen
and the screen turns o ) may
occur when starting to receive or
make calls.
