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
traffic 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.
