Poor quality
of calling
Please check if the sound volume is tuned
improperly
In an area with poor receiving condition,
example: basement, the signal might be weak.
Try reaching 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
cannot 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.
