Use only original manufacturer-approved accessories, or accessories that do not contain any metal

Use of non-original manufacturer-approved accessories may violate your local RF exposure guidelines and should be avoided.

Heed service markings

Except as explained elsewhere in the Operating or Service documentation, do not service any product yourself. Service needed on components inside these compartments should be done by an authorized service technician or provider.

Damage requiring service

Unplug the product from the electrical outlet and refer servicing to an authorized service technician or provider under the following conditions:

•Liquid has been spilled or an object has fallen into the product.

•The product has been exposed to rain or water.

•The product has been dropped or damaged.

•There are noticeable signs of overheating.

•The product does not operate normally when you follow the operating instructions.

The exposure standard for wireless mobile phones employs a unit of measurement known as the Specific Absorption Rate, or SAR.

For body worn operation, this phone has been tested and meets the FCC RF exposure guidelines when used with the standard accessories supplied or designated for this product. Use of other accessories may not ensure compliance with FCC RF exposure guidelines.

The standard incorporates a substantial margin of safety to give additional protection for the public and to account for any variations in usage. Normal conditions only ensure the radiative performance and safety of the interference. As with other mobile radio transmitting equipment, users are advised that for satisfactory operation of the equipment and for the safety of personnel, it is recommended that no part of the human body be allowed to come too close to the antenna during operation of the equipment.
