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
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.

Battery not
charging

damaged.
Contact the dealer.
The phone’s temperature is
below 32°F (0°C) or higher than
131°F (55°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
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.
The battery is depleted. In
high-temperature environments,
battery life will be shortened.
Use a new battery.
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.
