Q&A 
Q Why is there an echo when a connection is made with certain telephones in a certain area?
A This is called the ‘Echo Phenomenon’, where it occurs if connection volume is too high or caused by special properties (semi electronic telephone exchange) of the equipment on the other end.
QWhy does the phone heat up?
A The phone may get hot when there is a very long call duration or when games are played or even when surfing the Internet for a long time. This has no effect upon the life of the product or performance.
Q
A Phone may be set to ‘Vibration All’ or in ‘Silent All’ mode. In the Sound menu, please select Volume → Ringtone → Volume 1 ~ Volume 5 or Vol5&Vib.
QWhy does the battery life get shorter in standby mode?
A The battery is worn out. As time passes, the battery life gradually becomes shorter. If the battery lasts about half the amount of time as when first purchased, it’s time to purchase a new battery.
QWhy does the battery run out so quickly during normal use?
A It is due to the user environment or a large number of calls or weak signal.
