high or caused by special properties(semielectronic telephone
exchange) of the machine on the other end.
If connection is made for a significantly long duration, or game
and Internet and others are used for a long time, the phone may
become hot. This has no effect upon the life of the product or
performance.
Ringer Type may be set as "Silent" or "Light". Please select

If time for use of battery is short, it may be due to the user
environment, or large volume of calls, or weak signals.
