3. Check List
If you experience any problem while using your cell phone, please refer to
the following checklist. If the problem still persists, contact your dealer or
nearest service centre.
When the “Insert SIM Card” message appears:
Make sure the SIM card is correctly installed. Check to see if the SIM card is
working properly. If it does not work, try to clean the contact point of the card.
If it is out of order, take it to the nearest service centre.
When the “Handset locked enter password” message appears:
Enter the handset password. If you cannot remember the password, contact
the nearest service centre.
When the “Enter PIN1” message appears:
Input PIN1. If you cannot remember it, contact the nearest service centre.
You can still receive calls even if your cell phone becomes locked by
entering the incorrect PIN1 on three consecutive attempts.
When the “No service” or “Network failure” message appears:
Check the SSI (Signal Strength Indicator) state. If you cannot make a
connection in underground areas or in buildings where signal strength may
be low, try moving to another place. If you still cannot make a connection,
contact the nearest service centre.
When audio quality is poor:
End a call and try again.
When the other party cannot hear you speaking:
Your handset may be set to MUTE. Disable the MUTE function.
When battery lifetime is shorter than usual:
This may happen when you are in an area with low signal strength. Turn off
your handset when it is not in use. Change the battery when battery energy
is exhausted.
When your cell phone does not turn on:
Make sure your battery is charged. Check to see if your phone works while
recharging the battery.
When you are unable to send a message:
Either you are not registered to receive SMS service, or you may be in an
area where your network service provider cannot provide such service.
When you are unable to make a call:
Your phone may be set to “fixed dial.” Cancel the “fixed dial” function.
When you are unable to charge the battery:
This may be the result of one of the following three cases.
1. Your charger may be out of order. Contact your nearest dealer.
2. You may be attempting to use the phone in overly hot/cold temperature.
Try changing the charging environment.
3. Your battery may have not been connected to the charger properly. Check
the connector.
When you are unable to input data into the Phone Book:
Your Phone Book memory may be full. Try deleting some entries from your
Phone Book.
When you are unable to select a certain function:
You may not be subscribed to that function, or your network service provider
may be in an area where such service cannot be provided. Contact your
local service provider.
