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
