If you encounter problems while using the phone, or if it performs
erratically, you can consult the information in the following table. If a
particular problem cannot be resolved by using the following
information, contact the dealer where you purchased the phone.
Problem Possible causes Possible solution
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, because
there may be too much
network traffic to handle
additional calls.
Avoid using the
phone at such time,
or try again after
waiting a short time.
