Guidelines for safe and efficient use .......5
Important notice .....................................15
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 mobile phone model LG-D855 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 0.291 W/kg
(10 g) and when worn on the body is 0.269 W/Kg (10 g).
5
Guidelines for safe and efficient use
• 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

Guidelines for safe and efficient use
Anti-Theft Guide
You can set up your device to prevent other people from using it if it's been reset to
factory settings without your permission. For example, if your device is lost, stolen, or
wiped, only someone with your Google account or screen lock information can use the
device.
All you need to make sure your device is protected is:
• Set a screen lock: If your device is lost or stolen but you have a screen lock
set, the device can't be erased using the Settings menu unless your screen is
unlocked.
• Add your Google account on your device: If your device is wiped but you have
your Google account on it, the device can't finish the setup process until your
Google account information is entered again.
After your device is protected, you'll need to either unlock your screen or enter your
Google account password if you need to do a factory reset. This ensures that you or
someone you trust is doing the reset.
NOTE:
• Do not forget your Google account and password you had added to your
device prior to performing a factory reset. If you can't provide the account
information during the setup process, you won't be able to use the device
at all after performing the factory reset.
