Troubleshooting
To save time and avoid unnecessary cost, please conduct the following
checks before contacting our after-sale personnel:
1. Unable to turn on the phone: Check whether you have tapped and hold
the Power button for over three seconds. Check whether the battery is in
good contact. If not, remove the battery, re-install it, and turn on the
phone again. Check whether the battery runs out. If yes, charge it.
2. Poor signal: It is possibly because of where you are, for example, on the
basement or near a high-rise, that deteriorates the reachability of radio
waves. Please move to someplace with better signal reachability.
3. Echo or noise: The network trunk line of certain carriers may be in poor
quality. Please tap the hang-up icon and redial, so that you may switch to
another trunk line with better quality.
4. Unable to charge the battery: Your battery may fail. Please contact the
dealer.
5.SIM card error: The metal surface of the SIM card is dirty. Rub the metal
contact terminals with a clean dry cloth.
The SIM card is not installed properly. Install it again as specified in
the user manual.
The SIM card breaks down. Contact the network service provider.
6. Unable to enter anything into Phone Book: This is possible because
that your phone book memory is full. Please delete needless data from
Contacts.
We advise you to follow above instructions and precautionary
measures. Please take your phone to the nearest authorized service
center when it does not operate normally.
The actual situation of the phone usage is related to local
environment, SIM card and way of use.
