CONDITIONS OF USE
Battery
• Network configuration and phone usage will
affect talk-time and standby time.
Using the games or camera will hasten battery
consumption.
• When the battery charging alert is displayed on
the screen, charge the battery as soon as possible.
If you continue using your phone ignoring the alert,
the phone may cease to function, and all data and
settings you have stored may be lost.
• Before removing the battery from the phone, make
sure the phone is switched off.
• Replace and charge the new battery as soon as
possible after removing the old one.
• Recommended temperature for using and storing
batteries is approximately 20°C.
• The batteries’ performance is limited in low
temperatures, particularly below 0°C and the phone
may not work temporarily regardless of the amount
of remaining battery power.
• The battery can be charged and discharged hundreds
of times but it will eventually wear out. When the
operating time (talk-time and standby time) is
noticeably shorter than normal, it is time to buy a new
battery.
CAUTION
RISK OF EXPLOSION IF BATTERY IS REPLACED
BY AN INCORRECT TYPE,
DISPOSE OF USED BATTERIES ACCORDING

See “Battery Disposal” on page 23.
Camera Operation
• Learn picture quality, file formats, etc. beforehand.
The taken pictures can be saved in JPEG format.
• Be careful not to move your hand while taking
pictures.
If the phone moves while taking a picture, the picture
can become blurred. When taking a picture, hold the
phone firmly to prevent it from moving, or use the
delay timer.
• Clean the lens cover before taking a picture.
Fingerprints, oils, etc. on the lens cover hinder clear
focusing. Wipe them off with a soft cloth before
taking a picture.
Others
• As with any electronic storage unit, data may be lost
or corrupted under various circumstances.
• If the phone’s battery has been removed for some
time, or the phone has been reset, the unit’s clock and
calendar may be reinitialised. The date and time
should be updated in this case.
• Use only specified handsfree kits (supplied or
optional). Some phone’s functions may not work
when unauthorised handsfree kit is used.
