Troubleshooting
Security Problems Possible causes Possible solutions
The SIM card's PIN
code is blocked. You have entered an incorrect
PIN code three consecutive
times. Contact your service
provider to get the PUK
code.
System problems
Battery does not
charge. The battery or battery charger is
damaged. A possible cause for
this could be the use of
incorrect power adapter.
Use only the power
adapter that shipped
with your device.
The ambient temperature is
below 0°C or higher than 40°C. Adjust the battery
charging environment
to avoid extreme
temperatures.
Poor contact between the battery
and charger. Check all connectors
to ensure that all
connections have been
properly made.
The device does not
power on. The battery has no charge. Charge the device.
Shortened standby
time. The duration of standby time is
affected by your service provider’s
system configuration. The same
device used with different service
providers' systems does not have
the same duration of standby
time. If you are located in an
area where the network
signal is weak, move
your location to the area
where the network signal
is strong or temporarily
turn off your device if
needed.
If you are not able to connect
to the network, the device
continues to send out signals
as it attempts to locate a
base station. Doing this
consumes battery charge and
consequently shortens standby
time. Change your location
to one where the
network is accessible,
or temporarily turn off
your device or set it to
airplane mode.
