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
• 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.

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 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

• Do not tap the screen with a sharp object as it may damage the device.
7Guidelines for safe and efficient use
• 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.
• If your device 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 device, changes the colour of the product label inside your
device. Damage to your device as a result of exposure to liquid is not covered
under your warranty.
• A mobile device requires proper air circulation in order to dissipate heat. Direct
skin contact and inadequate circulation of air flow to the device may cause the
device to overheat. The device must be at least 1.0cm from between the user’s
body.
• Prevent dust of any other foreign substances from getting into the Charger/
USB cable port. It may cause heat or fire.
Efficient device operation
Electronics devices
All devices may receive interference, which could affect performance.
• Do not use your device near medical equipment without requesting permission.
Please consult your doctor to determine if operation of your device may
interfere with the operation of your medical device.

Custom-designed Features26
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 into an app or identifying yourself with
your fingerprint.
• You can use fingerprint data for user authentication. There is a
possibility that the fingerprint sensor might recognise a different but
very similar fingerprint as the same registered fingerprint. To strengthen
security, it is recommended that you use the pattern, PIN, or password
method for unlocking the screen.
• 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 has a fingerprint sensor. Be careful not to scratch or
damage the fingerprint sensor with metal objects such as coins or
keys.
• If there are foreign substances (sweat, lotion, water, dirt, grease, etc.)
on the fingerprint sensor or on the finger to be put on the sensor,
fingerprint recognition may not work properly. Wipe the sensor and the
finger clean and remove all moisture before putting the finger on the
sensor.
Custom-designed Features27
• If the finger’s surface is rough due to it being scarred or pruney from
water, the sensor may not be able to recognise the fingerprint. In such
a case, register another fingerprint.
• 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 fingerprint sensor.
• 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 a coin or a key before scanning fingerprints to
remove static electricity.
Registering fingerprints
You can register and save your fingerprint on the device to use fingerprint
identification.
Tap SettingsLock screen & securityFingerprints.

• A lock screen must be set to use this feature.
• If the screen lock is not active, configure the lock screen by following the

• Until the fingerprint registration is completed, move the same finger
around on the sensor little by little.
• Put the finger on the sensor. When you feel a vibration, remove the
finger from the sensor.
When the fingerprint registration is done, tap OK.
4
• Tap Add more to register another fingerprint. Since the fingerprint
recognition success rate depends on the condition of the registered
fingerprint, it is recommended that you register several different
fingerprints.
