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 0.393 W/kg

(10g)andwhenwornonthebodyis1.120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.

Fingerprint recognition

Fingerprint recognition overview

You must register your fingerprint on your device first before using the fingerprint recognition function.

You can use the fingerprint recognition function in the following cases:

• To unlock the screen.

• To view the locked content in the Gallery or QuickMemo+.

• Confirm a purchase by signing in to an app or identifying yourself with

your fingerprint.

• Your fingerprint can be used by the device for user identification. Very

similar fingerprints from different users may be recognised by the fingerprint sensor as the same fingerprint.

• If the device cannot detect your fingerprint, or you forgot the value

specified for registration, visit the nearest LG Customer Service Centre with your device and ID card.

Precautions for fingerprint recognition

Fingerprint recognition accuracy may decrease due to a number of reasons. To maximise the recognition accuracy, check the following before using the device.

• The device’s Power/Lock key has a fingerprint sensor. Ensure that the

Power/Lock key is not damaged by a metallic object, such as coin or key.

• When water, dust or other foreign substance is on the Power/Lock key

or your finger, the fingerprint registration or recognition may not work. Clean and dry your finger before having the fingerprint recognised.

• A fingerprint may not be recognised properly if the surface of your

finger has a scar or is not smooth due to being soaked in water.

Custom-designed Features 28

• If you bend your finger or use the fingertip only, your fingerprint may

not be recognised. Make sure that your finger covers the entire surface of the Power/Lock key.

• Scan only one finger for each registration. Scanning more than one

finger may affect fingerprint registration and recognition.

• The device may generate static electricity if the surrounding air is

dry. If the surrounding air is dry, avoid scanning fingerprints, or touch a metallic object such as coin or key before scanning fingerprints to remove static electricity.

Registering fingerprints

You can register and save your fingerprint on the device to use fingerprint identification.
