Poor quality
of calling
Please check if the sound volume is tuned
improperly ;
In an area with poor receiving condition, for
example: basement, the signal might be
weak. Try searching a location with stronger
signal reception and call again;
While using the mobile phone in the peak
period of communication, like commute
time, you may be unable to call because of
line congestion.
Standby
duration
shortened
The standby duration is relative to the
system setting of network. While the mobile
phone is in an area with poor signal strength
and can not receive the signal, the handset
will continuously search for a base station.
This will significantly reduce battery charge.
It is recommended that you turn off your
mobile in area with no signal reception to
save battery.
Need replacing the battery. Please change a
new battery.
