If you encounter problems while using the phone, or if it performs
erratically, you can consult the information in the following table. If a
particular problem cannot be resolved by using the following
information, contact the dealer where you purchased the phone.
| Problem |
Possible causes |
Possible solution |
| Poor reception |
The network signal is too weak at your current location, for
example, in a basement or near a tall building, because wireless
transmissions cannot effectively reach it. |
Move to a location where the network signal can be properly
received. |
| The network is busy at the current time, for example, during peak
times, because there may be too much network traffic to handle
additional calls. |
Avoid using the phone at such time, or try again after waiting a
short time. |
| You are too far away from a base station for your service provider. |
You can request a service area map from your service provider. |
| Echo or noise |
Poor network trunk quality on the part of your service provider. |
Press the ending key and dial again. You may be switched to a
better-quality network trunk or phone line. |
| Poor local telephone line quality |
Press the ending key and dial again. You may be switched to a
better-quality network trunk or phone line. |
| Battery will not charge. |
The battery or battery charger is damaged. |
Contact the dealer. |
| The temperature of the phone is below 0°C or higher than 45°C. |
Adjust the battery charging environment to avoid extremes of
temperature. |
| Poor contact between the battery and charger. |
Check all connectors to make sure all connections have been properly
made. |
| Shortened standby time |
The standby time is related to your service provider system
configuration. The same phone used with different service providers’
systems will not provide exactly the same length of standby time. |
If you are located in an area where signaling is weak, temporarily
switch off the phone. |
| The battery is depleted. In high temperature environments, battery
life will be shortened. |
Use a new battery. |
| If you are not able to connect to the network, the phone will
continue to send out signals as it attempts to locate a base station.
Doing so consumes battery power and will consequently shorten standby
time. |
Change your location to one where the network is accessible, or
temporarily turn off your phone. |
| You cannot switch your phone on. |
Battery power has been depleted. |
Recharge the battery. |
| SIM card error |
SIM card malfunction or damage |
Take the SIM card to your service provider for testing. |
| SIM card is inserted improperly. |
Insert the SIM card properly. |
| Debris on the SIM card contacts |
Use a soft and dry cloth to clean the SIM card contacts. |
| Unable to connect to the network. |
SIM card invalid. |
Contact your service provider. |
| You are not within the service area of the network. |
Check the service area with your service provider. |
| Poor signal. |
Move to an open space, or if you are inside a building, move closer
to a window. |
| You cannot answer incoming calls. |
You have activated the call barring feature. |
Go to Settings > Call Setup > Call Barring, and then select Cancel
All. |
| You cannot make outgoing calls. |
You have activated the call barring feature. |

All. |

You have entered an incorrect PIN code three consecutive times. |
Contact your service provider. If the service provider provides the
PUK code of the SIM card, use the PUK code to unlock the SIM card. |
| Unable to enter information into the phone book. |
The memory of the phone book is already full. |
Delete unnecessary data from the phone book. |
| Unable to select certain features. |
Your service provider does not support these features, or you have
not applied for services that provide these features. |
Contact your service provider. |
