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.

Information about the RF exposure from FCC

In August 1996, the Federal Communications Commission (FCC) of the United States, with its action in Report and Order FCC 96-326, adopted an updated safety standard for human exposure to radio frequency (RF) electromagnetic energy emitted by FCC regulated transmitters. Those guidelines are consistent with the safety standard previously set by both international and U.S. standards. The design of this device complies with FCC guidelines and these international standards.

Part 15.19 statement

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and

(2) this device must accept any interference received, including interference that

6Guidelines for safe and efficient use

Body-worn Operation

This device was tested for typical bodyworn operations with the back of the device kept 0.39 inches (1cm) between the user’s body and the back of the device. To comply with FCC RF exposure requirements, a minimum separation distance of

0.39 inches (1cm) must be maintained between the user’s body and the back of the device.

Any beltclips, holsters, and similar accessories containing metallic components may not be used. Body-worn accessories that cannot maintain 0.39 inches (1cm) separation distance between the user’s body and the back of the device, and have not been tested for typical body-worn operations may not comply with FCC RF exposure limits and should be avoided.

Part 15.105 Statement

This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

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. Ensure that the fingerprint sensor

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

• When water, dust or other foreign substance is on the fingerprint

sensor 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 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 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.
