HTC Shadow Cell Phone User Manual


 
Appendix  239
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.
