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 0.742 W/kg
(1g) and when worn on the body is 0.411 W/kg (1g) at 15 mm, which is 100%
compliant with Indian Standards and Safe.
• This device meets RF exposure guidelines when used either in the normal use
position against the ear or when positioned at least 15 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 15 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.

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.
• At the bottom centre of the product’s screen, there is a built-in sensor
that recognises fingerprints. 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.
• 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.
