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 authorized
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-D838 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 (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 for use at the ear is 0.305 W/kg
(10 g) and when worn on the body is 0.334 W/Kg (10 g).
Guidelines for safe and efficient use

6
• 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.
• 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.
Guidelines for safe and efficient use

7
• 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 affect the
information on the magnetic strips.
• Do not tap the screen with a sharp object as it may damage the phone.
• Do not expose the phone to liquid or moisture.
• Use 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 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.

Efficient phone operation
Electronics devices
All mobile phones may receive 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.
• Use your phone in temperatures between 0ºC and 40ºC, if possible. Exposing your
phone to extremely low or high temperatures may result in damage, malfunction, or
even explosion.
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.
• 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 of particular
importance when near roads.
Guidelines for safe and efficient use

9
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.

10
Potentially explosive atmospheres
• Do not use your phone at a refueling point.
• Do not use near fuel or chemicals.
• Do not transport or store flammable gas, liquid or explosives in the same
compartment of your vehicle as your mobile phone or accessories.
In aircraft
Wireless devices can cause interference in aircraft.
• Turn your mobile phone off before boarding any aircraft.
• Do not use it on the ground without permission from the crew.
Children
Keep the phone in a safe place out of the reach of small children. It includes small parts
which may cause a choking hazard if detached.
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.
