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.
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.
Unable to connect
to the network
You are not within the network’s service
area.
Check the service area with your service
provider.
