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
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.
