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 points 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:
InputPIN1. If you cannot remember it, contact the nearest service centre. You can still receive calls even if your cell phone becomes locked after 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.
