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
Poor
reception
Echo or noise
Possible causes
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.
The network is busy at the
current time (for example,
during peak times, there
may be too much network
traffic to handle additional
calls).
You are too far away from a
base station for your service
provider.
The network link quality is
poor on the part of your
service provider.
The quality of the phone
line that you are calling is
poor.

Possible solution
Move to a location

after waiting a
short time.
You can request a

provider.
