Troubleshooting
If you encounter problems while using the phone, or if it performs abnormally,
you can refer to the chart below. If your particular problem cannot be
resolved using the information in the chart, 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,
there may be too much network
trafc to handle additional calls).
Avoid using the phone at such
times, 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 link quality on the part
of your service provider.
End the call and dial again. You
may be switched to a better-
quality network link or phone
line.
Poor local telephone line quality. End the call and dial again. You
may be switched to a better-
quality network link or phone
line.
