228 Appendix
Your device has an internal antenna. Use only the supplied integral antenna.
Use of unauthorized or modified antennas may impair call quality and
damage the 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 RF
energy is within the guidelines set forth in the relevant standards; always
use your device 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 device to
operate at a higher power level than needed. Avoiding contact with the
antenna area when the 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 and FCC requirements). For body
worn operation, to maintain compliance with FCC RF exposure guidelines,
use only original manufacturer approved accessories. When carrying
the phone while it is on, use the specific original manufacturer supplied
or approved carrying case, holster, or other body-worn accessory. SAR
compliance for body-worn operations is restricted to belt-clips, holsters, or
similar accessories that have no metallic component in the assembly and
which provide at least 1.5 cm separation between the device and the users
body.
