week, since overcharging may shorten its lifetime. If left
unused, a fully charged battery will discharge itself over
time.
Do not paint your phone as this can clog its moving parts
and prevent operation.
Only use the antenna supplied or an approved replacement
antenna. Unauthorised antennae, modifications or
attachments could damage the phone and may violate
regulations governing use of mobile phones.
Keep all USIM Cards out of children's reach.
Use your phone battery only for its intended purpose, and
never use any charger or battery which is damaged or worn
out.
Never allow the battery terminals to short circuit, as this can
cause damage to the battery or to the connecting object (a
short circuit can occur if a metallic object such as a coin,
clip or pen causes direct connection between the + and -
terminals of the battery). Therefore, always take adequate
140
precautions when carrying a spare battery in a purse or
pocket.
Batteries must be recycled or disposed of properly and
according to your local regulations, and must never be
disposed of in household waste. Never dispose of batteries
in a fire.
When you disconnect the power cord of any accessory,
including the charger, grasp and pull the plug, not the cord.
For good operation times, discharge
an NiMH battery from time to time by leaving your phone
switched on until it turns itself off.
Do not attempt to open the casing on your phone or its
battery. Non-expert handling may damage it.
Do not drop, knock or shake the phone. Rough handling
can break the internal circuit boards.
Do not use harsh chemicals, cleaning solvents, or strong
detergents to clean your phone. Wipe it with a soft cloth
slightly dampened in a mild soap and water solution.
Do not store it in hot areas. High temperatures can shorten
the life of electronic devices, damage batteries and warp or
melt certain plastics.
Do not store your phone in cold areas. When it warms up
(to its normal temperature) moisture can form inside the
phone which may damage electronic circuit boards.
All of the above suggestions apply equally to your phone,
battery, charger or any accessory. If any of them is not working
properly, contact Orange customer services on 07973 100 150
or, if you are a pay as you go customer, on 07973 100 451,
from any other phone for assistance.

radio waves and
your phone
Specific absorbtion rate, or SAR, is an internationally
accepted way of measuring how much radio frequency (RF)
energy is absorbed by the body when a mobile phone is
used.
All phones on the Orange network are designed by the
phone manufacturers to comply with the relevant
recommendations and standards. Orange believes that new
and existing customers should be fully informed about SAR.
The SAR value for your LG U8150 is 0.638W/kg (10g).
