or caused by special properties (semi electronic telephone
exchange) of the machine on the other end.

the phone may become hot. This is perfectly normal and has no
effect upon the life of the product or performance.

The phone is set to 'Vibrate'or 'Silent' in the Profiles menu.

A
Batteries have a limited life. When the battery lasts for half its
original time, it requires replacement. Only use authorised
replacement parts.
Q
Usage time of battery becomes shorter.

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