For your safety and proper maintenance.
The following list shows how to maintain your mobile phone as well as
precautions.
- Keep your cell phone and its accessories out of the reach of children.
- Keep your mobile phone in dry condition and use it in normal temperature.
Temperatures higher than 55 ° C (131 ° F ) or lower than -20 C (-4 ° F ) may
damage your phone.
- Do not use or store your phone in dusty, dirty areas.
- Do not attempt to disassemble your phone.
- Do not drop or cause severe impact to the phone.
- Do not use chemical products, cleaning solvents or detergents to clean your
phone.
- If your phone does not work properly, contact your dealer immediately.
- Use only authorized batteries, battery chargers and accessories. Any malfunction
or damage caused by the use of unauthorized batteries, battery chargers and
accessories will void the limited product warranty.
- Ensure that the grounding points of the battery and battery charger are not in
direct contact with conductive objects.
If you experience problems while using your mobile phone, please refer to the
following checklist. If the problem persists, contact your dealer or nearest service
center.
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 cleaning the contact point of the card.
If it is out of order, take it to the nearest service center.
When the “Handset locked enter password” message appears:
Enter the lock code. If you cannot remember the lock code, contact the nearest
service center.
When the “Enter PIN1” message appears:
Enter the PIN1. If you cannot remember it, contact the nearest service center. You
can still receive calls even if your phone becomes locked as a result of entering
incorrect PIN1 three times in a row.
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
center.
When call quality is poor:
End the phone call and try again.
When the other party cannot hear you speaking:
Your phone may be set to MUTE. Disable the MUTE function by converting to the
UNMUTE mode.
