Guidelines for safe and efficient 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 device 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 device transmitting at its highest certified

power level in all used frequency bands.

• While there may be differences between the SAR levels of various LG device

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10goftissue.

• The highest SAR value for this model tested for use at the ear is X.XXX W/kg

(10g)andwhenwornonthebodyisX.XXX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 5 mm 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 5 mm 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.

7Guidelines for safe and efficient use

Information about the RF exposure from FCC

In August 1996, the Federal Communications Commission (FCC) of the United

States, with its action in Report and Order FCC 96-326, adopted an updated safety

standard for human exposure to radio frequency (RF) electromagnetic energy

emitted by FCC regulated transmitters. Those guidelines are consistent with the

safety standard previously set by both international and U.S. standards. The design

of this device complies with FCC guidelines and these international standards.

Part 15.19 statement

This device complies with part 15 of the FCC Rules. Operation is subject to the

following two conditions:

(1) This device may not cause harmful interference, and

(2) this device must accept any interference received, including interference that

may cause undesired operation.

Part 15.21 Statement

Changes or modifications not expressly approved by the manufacturer could void

the user’s authority to operate the equipment.

8Guidelines for safe and efficient use

Body-worn Operation

This device was tested for typical bodyworn operations with the back of the device

kept 0.39 inches (1cm) between the user’s body and the back of the device. To

comply with FCC RF exposure requirements, a minimum separation distance of

0.39 inches (1cm) must be maintained between the user’s body and the back of

the device.

Any beltclips, holsters, and similar accessories containing metallic components

may not be used. Body-worn accessories that cannot maintain 0.39 inches (1cm)

separation distance between the user’s body and the back of the device, and have

not been tested for typical body-worn operations may not comply with FCC RF

exposure limits and should be avoided.

Part 15.105 Statement

This equipment has been tested and found to comply with the limits for a class

B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed

to provide reasonable protection against harmful interference in a residential

installation. This equipment generates uses and can radiate radio frequency energy

and, if not installed and used in accordance with the instructions, may cause

harmful interference to radio communications. However, there is no guarantee that

interference will not occur in a particular installation. If this equipment does cause

harmful interference or television reception, which can be determined by turning

the equipment off and on, the user is encouraged to try to correct the interference

by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which

the receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

Product care and maintenance

• Use only in-box accessories which are authorised by LG. LG does not guarantee

any damage or failure which is caused by third party accessories.

• 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.

9Guidelines for safe and efficient use

• 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 device in any area where you are required to by special

regulations. For example, do not use your device in hospitals as it may affect

sensitive medical equipment.

• Do not handle the device with wet hands while it is being charged. It may cause

an electric shock and can seriously damage your device.

• 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 device when it is on soft furnishings.

• The device should be charged in a well ventilated area.

• Do not subject this unit to excessive smoke or dust.

• Do not keep the device 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 device.

• Do not expose the device 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 device 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

device during or immediately after operation.
