Guidelines for safe and efcient use
Please read these simple guidelines. Not following these guidelines may
be dangerous or illegal.
Should a fault occur, a software tool is built into your device that will
gather a fault log. This tool gathers only data specific to the fault, such as
signal strength, cell ID position in sudden call drop and applications loaded.
The log is used only to help determine the cause of the fault. These logs
are encrypted and can only be accessed by an authorised LG Repair centre
should you need to return your device for repair.
Exposure to radio frequency energy
Radio wave exposure and Specific Absorption Rate (SAR) information.
This mobile phone model LG-K420ds 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
LGphonemodels,theyarealldesignedtomeettherelevant
guidelines for exposure to radio waves.

•
This device meets RF exposure guidelines when used either in the
normal use position against the ear or when positioned at least
15mmawayfromthebody.Whenacarrycase,beltcliporholder
is used for body-worn operation, it should not contain metal and
shouldpositiontheproductatleast15mmawayfromyourbody.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

Always use genuine LG batteries, chargers and accessories approved
for use with this particular device model. The use of any other types
may void any approval or warranty applying to the device and may be
dangerous.
•
Some contents and illustrations may differ from your device without
prior notice.
•
Do not disassemble this unit. Take it to a qualified service technician
when repair work is required.
•
Repairs under warranty, at LG's discretion, may include replacement
parts or boards that are either new or reconditioned, provided that
they have functionality equal to that of the parts being replaced.
•
Keep away from electrical appliances such as TVs, radios and personal
computers.
•
The unit should be kept away from heat sources such as radiators or
cookers.
•
Do not drop.
•
Do not subject this unit to mechanical vibration or shock.
•
Switch off the phone in any area where you are required to by special
regulations. For example, do not use your phone in hospitals as it may
affect sensitive medical equipment.
6
•
Do not handle the phone with wet hands while it is being charged. It
may cause an electric shock and can seriously damage your phone.
•
Do not charge a handset near flammable material as the handset can
become hot and create a fire hazard.
•
Use a dry cloth to clean the exterior of the unit (do not use solvents
such as benzene, thinner or alcohol).
•
Do not charge the phone when it is on soft furnishings.
•
The phone should be charged in a well ventilated area.
•
Do not subject this unit to excessive smoke or dust.
•
Do not keep the phone next to credit cards or transport tickets; it can

cracked glass. Damage to the glass display due to abuse or misuse is
not covered under the 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.
•
If your phone gets wet, immediately unplug it to dry off completely.
Do not attempt to accelerate the drying process with an external
heating source, such as an oven, microwave or hair dryer.
•
The liquid in your wet phone, changes the colour of the product label
inside your phone. Damage to your device as a result of exposure to
liquid is not covered under your warranty.

•
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 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.
Blasting area
Do not use the phone where blasting is in progress. Observe restrictions
and follow any regulations or rules.
