Guidelines for safe and
efficient use
Please read these simple guidelines. Not following these
guidelines may be dangerous or illegal.
Exposure to radio frequency energy
Radio wave exposure and Specific Absorption Rate (SAR)
information.
This mobile phone model LG-E960 has been designed to comply
with applicable safety requirements for exposure to radio
waves. These requirements are based on scientific guidelines
that include safety margins designed to assure the safety of all
persons, regardless of age and health.
The radio wave exposure guidelines employ a unit of
measurement known as the Specific Absorption Rate, or
SAR. Tests for SAR are conducted using standardised
methods with the phone transmitting at its highest certified
power level in all used frequency bands.

While there may be differences between the SAR levels of
various LG phone models, they are all designed to meet the
relevant guidelines for exposure to radio waves.
The SAR limit recommended by the International
Commission on Non-Ionizing Radiation Protection (ICNIRP)
is 2 W/kg averaged over 10g of tissue.
The highest SAR value for this model phone tested by DASY4
for use at the ear is 0.407 W/kg (10g) and when worn on the
body is 0.479 W/Kg (10g).
This device meets RF exposure guidelines when used either
in the normal use position against the ear or when positioned
at least 1.5 cm away from the body. When a carry case, belt
clip or holder is used for body-worn operation, it should
not contain metal and should position the product at least
1.5 cm away from your body. In order to transmit data files or
messages, this device requires a quality connection to the
network. In some cases, transmission of data files or mes-
sages may be delayed until such a connection is available.
Ensure the above separation distance instructions are fol-
lowed until the transmission is completed.

without requesting permission. Avoid placing the phone over
pacemakers, for example, in your breast pocket.
Some hearing aids might be disturbed by mobile phones.
Minor interference may affect TVs, radios, PCs etc.
Road safety
Check the laws and regulations on the use of mobile phones in
the area when you drive.
Do not use a hand-held phone while driving.

can cause the air bag to fail or cause serious injury due to
improper performance.
If you are listening to music whilst out and about, please
ensure that the volume is at a reasonable level so that
you are aware of your surroundings. This is of particular
importance when near roads.

Avoid damage to your hearing
To prevent possible hearing damage, do not listen at high
volume levels for long periods.
Damage to your hearing can occur if you are exposed to loud
sound for long periods of time. We therefore recommend that
you do not turn on or off the handset close to your ear. We also
recommend that music and call volumes are set to a reasonable
level.
When using headphones, turn the volume down if you cannot
hear the people speaking near you, or if the person sitting
next to you can hear what you are listening to.
NOTE: Excessive sound pressure from earphones and
headphones can cause hearing loss.
Glass Parts
Some parts of your mobile device are made of glass. This glass
could break if your mobile device is dropped on a hard surface or
receives a substantial impact. If the glass breaks, do not touch
or attempt to remove it. Stop using your mobile device until the
glass is replaced by an authorised service provider.

Emergency calls
Emergency calls may not be available on all mobile networks.
Therefore you should never depend solely on your phone for
emergency calls. Check with your local service provider.
Battery information and care
You do not need to completely discharge the battery before
recharging. Unlike other battery systems, there is no memory
effect that could compromise the battery's performance.
Use only LG batteries and chargers. LG chargers are
designed to maximise the battery life.
Do not disassemble or short-circuit the battery.
Recharge the battery if it has not been used for a long time to
maximise usability.
Do not expose the battery charger to direct sunlight or use it
in high humidity, such as in the bathroom.
Do not leave the battery in hot or cold places, as this may
deteriorate battery performance.
There is risk of explosion if the battery is replaced with an
incorrect type.
Dispose of used batteries according to the manufacturer's
instructions. Please recycle when possible. Do not dispose
as household waste.
If you need to replace the battery, take it to the nearest
authorised LG Electronics service point or dealer for
assistance.
