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 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 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.
Poor local telephone line quality.
End the call and dial again. You may be
switched to a better-quality network link or
phone line.

select certain
features
Your service provider does not
support these features, or you have
not applied for services that provide
these features.
