Care and maintenance
Your phone has been designed and manu-
factured to the highest of standards and
should be treated with great care. The sug-
gestions below will help you to enjoy your
phone for many years.
• Protect your phone from moisture and hu-
midity. Precipitation, humidity and liquids
contain minerals that will corrode electron-
ic circuits. Nevertheless, should your
phone become wet, disconnect it immedi-
ately from the power supply to avoid elec-
tric shock. Do not place your phone (even
to dry it) on/in a source of heat such as
a microwave oven, oven or radiator. The
phone may become overheated and
possibly explode.
• Do not use or store the phone in dusty,
dirty areas. Its moving parts may be
damaged and the casing may become
deformed and discoloured.
• Do not store your phone in hot environ-
ments (e.g. vehicle instrument panel in the
summer). High temperatures can shorten
the life of electronic devices, damage bat-
teries and warp or melt certain plastics.
• Do not store your phone in cold environ-
ments. When the phone warms up again
(to its normal ambient temperature), mois-
ture can form inside the phone, which may
damage electronic circuit boards.
• Do not drop, knock or shake your phone.
Rough handling can damage internal cir-
cuit boards!
• Do not use harsh chemicals, cleaning
solvents, or strong detergents to clean
the phone!
The suggestions given above apply equally
to your phone, battery, charger and all ac-
cessories. If any of these parts is not working
properly, obtain fast and reliable help at our
service centres.
Battery quality statement
The capacity of your mobile phone battery
will reduce each time it is charged/emptied.
Storage at too high or low temperatures will
also result in a gradual capacity loss. As
a result the operating time of your mobile
phone may be considerably reduced, even
after a full recharge of the battery.
Regardless of this, the battery has been de-
signed and manufactured so that it can be
recharged and used for six months after the
purchase of you mobile phone. After six
months, if the battery is clearly suffering from
loss of performance, we recommend that
you replace it. Please buy only original
batteries.
Display quality
declaration
For technological reasons, a few small dots
with different colours may appear in the dis-
play in exceptional cases.
Just remember that the appearance of
brighter or darker dots generally does not
mean that a fault has occurred.
