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.
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.
Problem Possible Causes Possible Solution
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.
