Troubleshooting
If you encounter problems while using the phone, or if it performs
erratically, you can consult the information in 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 cause 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 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
network operator.
You can request a service
area map from your network
operator.
Echo or noise
•
Poor network trunk quality
on the part of your
network operator.
Hang up the phone and dial
again. You may be switched
to a better-quality network
trunk or phone line.
•
Poor local telephone line
quality.
