Safety Precautions and Conditions of Use 124
Battery
• Use your phone only with batteries, chargers and
accessories recommended by the manufacturer. The
manufacturer disclaims any liability for damage caused
by the use of other chargers, batteries or accessories.
• Network configuration and phone usage will affect
talk-time and stand-by 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 at any moment.
• 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.
• Do not touch the battery terminals. Batteries can cause
damage, injury or burns if a conductive material touches
exposed terminals. When the battery is detached from
the phone, use a cover made of non-conductive material
for keeping and carrying the battery safely.
• 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.
• Exposing the phone to extreme temperatures will
shorten battery life.
• The battery can be charged and discharged hundreds
of times but it will eventually wear out. When the
operating time (talk-time and stand-by 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
TO THE INSTRUCTIONS
See “Battery Disposal” on page 13.
Aerial Care
• Do not touch the aerial unnecessarily, whilst using
the mobile phone. If it is held, call quality may be
hindered leading to shortened talk-time and stand-by
time because the mobile phone may have to operate
on a higher power level than is necessary.
• Use only the aerial supplied or one approved by
Sharp for your mobile phone. Using unauthorised or
modified aerials may damage the mobile phone.
Moreover, since the mobile phone may violate the
appropriate regulations, it may lose performance or
exceed the limitation of SAR levels.
