Appendix I Troubleshooting
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
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, 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.
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 trunk quality on
the part of your service
provider.
Press the ending key and dial
again. You may be switched to a
better-quality
network
trunk
or
phone line.
Poor local telephone line
quality
Press the ending key and dial
again. You may be switched to a
better-quality
network
trunk
or
phone line.
Battery not
charging
properly
The battery or battery charger
is damaged.
Contact the dealer.
The temperature of the phone
is below -10°C or higher than

charging

all connections have been properly
made.
