NEXUS 4 SAFETY & WARRANTY 1
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
ensure 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 (10 g) and when worn on the
body is 0.479 W/kg (10 g).
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 messages may be delayed until such a connection is
available. Ensure the above separation distance instructions
are followed until the transmission is completed.
Product care and maintenance
WARNING: Only use batteries, chargers and accessories
approved for use with this particular phone model. The use
of any other types may invalidate any approval or warranty
applying to the phone and may be dangerous.
Do not disassemble this unit. Take it to a qualified service
technician when repair work is required.

Use the accessories like earphones cautiously. Do not touch
the antenna unnecessarily.
Do not use, touch or attempt to remove or fix broken, chipped
or cracked glass. Damage to the glass display due to abuse
or misuse is not covered under the manufacturer’s warranty.
Your phone is an electronic device that generates heat
during normal operation. Extremely prolonged, direct skin
contact in the absence of adequate ventilation may result
in discomfort or minor burns. Therefore, use care when
handling your phone during or immediately after operation.
Efficient phone operation
Electronics devices
All mobile phones may get interference, which could affect
performance.
Do not use your mobile phone near medical equipment
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.

Give full attention to driving.
Pull off the road and park before making or answering a call
if driving conditions so require.
RF energy may affect some electronic systems in your
vehicle such as car stereos and safety equipment.
When your vehicle is equipped with an air bag, do not
obstruct with installed or portable wireless equipment. It
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 particularly
imperative 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.

Use your mobile phone to call emergency services for
yourself or others in the case of fire, traffic accident or
medical emergencies;
- Australia Dial (0-0-0)

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 pack.
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 the battery performance.
There is risk of explosion if the battery is replaced by an
incorrect type.
If you need to replace the battery, take it to the nearest
authorised LG Electronics service point or dealer for
assistance.
Always unplug the charger from the wall socket after
the phone is fully charged to save unnecessary power
consumption of the charger.
Actual battery life will depend on network configuration,
product settings, usage patterns, battery and environmental
conditions.
Make sure that no sharp-edged items such as animal’s teeth
or nails, come into contact with the battery. This could cause
a fire.
