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
Possible causes
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.
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.
Echo or noise
Poor network link quality on the part
of your service provider.
Poor local telephone line quality.
Unable to select
Your service provider does not
certain features
support these features, or you have
not applied for services that provide
these features.

Possible solution
Move to a location where the
network signal can be properly
received.
Avoid using the phone at such
times, or try again after waiting a
short time.
You can request a service area
map from your service provider.
End the call and dial again. You
may be switched to a better-
quality network link or phone line.

Problem
Possible causes
Battery not
The battery or battery charger is
charging
damaged.
The phone's temperature is below
0°C or higher than 45°C.
Poor contact between the battery
and charger.
Shortened
The standby time is related to your
standby time
service provider system configuration.
The same phone used with different
service providers' systems will not
provide exactly the same length of
standby time.
The battery is depleted. In high
temperature environments, battery
life will be shortened.
If you are not able to connect to
the network, the phone will continue
to send out signals as it attempts
to locate a base station. Doing so
consumes battery power and will
consequently shorten standby time.
Cannot turn
Battery power has been depleted.
