Exposure to radio frequency energy
Radio wave exposure and Specific Absorption Rate (SAR) information.
This mobile phone model LG-D686 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 0.258 W/kg
(10g) and when worn on the body is 0.654 W/Kg (10g).
• 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

Your Home screen
Touch Screen tips
Here are some tips on how to navigate on your phone.
Tap or touch – A single finger tap selects items, links, shortcuts and letters on the
on-screen keyboard.
Touch and hold – Touch and hold an item on the screen by touching it and not lifting
your finger until an action occurs. For example, to open a contact's available options,
touch and hold the contact in the Contacts list until the context menu opens.
Drag – Touch and hold an item for a moment and then, without lifting your finger, move
your finger on the screen until you reach the target position. You can drag items on the
Home screen to reposition them.
Swipe or slide – To swipe or slide, quickly move your finger across the surface of the
screen, without pausing when you first touch it (so you don’t drag an item instead). For
example, you can slide the screen up or down to scroll through a list, or browse through
the different Home screens by swiping from left to right (and vice versa).
Double-tap – Double-tap to zoom on a webpage or a map. For example, quickly
double-tap a section of a webpage to adjust that section to fit the width of the screen.
You can also double-tap to zoom in and out while viewing the picture.
Pinch-to-Zoom – Use your index finger and thumb in a pinching or spreading motion
to zoom in or out when using the browser or Maps, or when browsing pictures.
Rotate the screen – From many applications and menus, the orientation of the screen
adjusts to the device's physical orientation.
NOTE:
To select an item, touch the center of the icon.
Do not press too hard; the touch screen is sensitive enough to pick up a light,
yet firm touch.
Use the tip of your finger to touch the option you want. Be careful not to
touch any other keys.
