Sharp SH1810C User Manual page 129

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 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 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 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 TO THE INSTRUCTIONS
See "Battery Disposal" on page 14.
Aerial Care
• Do not cover the hinge area of the phone (p. 13, No. 31) with
your hand when in use as this may interfere with the
performance of the built-in aerial. Call quality may deteriorate
leading to shortened talk-time and standby time because the
mobile phone has 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.
• To avoid impaired performance, do not damage the aerial of the
mobile phone.
• To avoid interfering with blasting operations, please turn off the
mobile phone in a blasting area or in a place where a "turn off
two-way radio" sign is posted.
