Problem Possible Causes Possible Solution
Battery not
charging
The battery or battery charger is
damaged.
Contact the dealer.
The phone’s temperature is
below 32°F (0°C) or higher than
113°F (45°C).
Adjust the battery charging
environment to avoid extremes of
temperature.
Poor contact between the
battery and charger.
Check all connectors to make
sure all connections have been
properly made.
Shortened
standby time
The standby time is related to
your service provider system
configuration. The same phone
used with different service
providers’ systems will not
provide exactly the same length
of standby time.
If you are located in an area where
signaling is weak, temporarily
power off the phone.
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.
Change your location to one
where the network is accessible,
or temporarily turn off your
phone.
Cannot turn
your phone on
Battery power has been
depleted.
Recharge the phone’s battery.
Unable to
connect to the
network
You are not within the network’s
service area.
Check the service area with your
service provider.
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.
Unable to
select certain
features
Your service provider does not
support these features, or you
have not applied for services
that provide these features.
Contact your service provider.
