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 can not 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.
