4 Quick Start Guide

The exposure standard for wireless mobile phones employs a unit

of measurement known as the Specific Absorption Rate, or SAR. The

standard incorporates a substantial margin of safety to give additional

protection for the public and to account for any variations in usage.

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.

Your phone has an internal antenna. Use only the supplied integral

antenna. Use of unauthorized or modified antennas may impair call

quality and damage your phone, causing loss of performance and

SAR levels exceeding the recommended limits as well as result in non-

compliance with local regulatory requirements in your country.

To assure optimal phone performance and ensure human exposure

to Radio Frequency energy is within the guidelines set forth in the

relevant standards; always use your phone only in its normal-use

position. Do not touch or hold the antenna area unnecessarily when

placing or receiving a phone call. Contact with the antenna area may

impair call quality and cause your phone to operate at a higher power

level than needed. Avoiding contact with the antenna area when

your phone is IN USE optimizes the antenna performance and the

battery life.

Tests for SAR are conducted using standard operating positions

specified by the FCC with the phone transmitting at its highest

certified power level in all tested frequency bands. Although the SAR

is determined at the highest certified power level, the actual SAR level

of the phone while operation can be well below the maximum value.

This is because the phone is designed to operate at multiple power

levels so as to use only the power required to reach the network.

In general, the closer you are to a wireless base station antenna,

the lower the power output. Before a phone model is available for

sale to the public, it must be tested and certified to the FCC that it

does not exceed the limit established by the government-adopted

requirement for safe exposure. The tests are performed in positions

and locations (for example, at the ear and worn on the body) as

required by the FCC for each model. (Bodyworn measurements may

differ among phone models, depending upon available accessories
