Questions and Answers
If you encounter problems while using the phone, or if it performs erratically, you can consult the
information in 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 trunk quality on the part of
your service provider.
End the call and dial again. You may be switched
to a better-quality network trunk or phone line.
• Poor local telephone line quality.
End the call and dial again. You may be switched
to a better-quality network trunk 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 will not
charge.
• The battery or battery charger is damaged.
Contact the dealer.
• The phone’s temperature is below 0°C or
higher than 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.
You cannot
switch your
phone on.
Battery power has been depleted.
Recharge the phone's battery.
UIM card error
• UIM card malfunction or damage.
Take the UIM card to your service provider for
testing.
