202 Section 4B. Regulatory Notices
Hearing devices may also be rated. Your hearing device manufacturer or hearing health professional may
help you find this rating. Higher ratings mean that the hearing device is relatively immune to interference
noise. The hearing aid and wireless phone rating values are then added together. A sum of 5 is considered
acceptable for normal use. A sum of 6 is considered for better use. A sum of 8 is considered for best use.
In the above example, if a hearing aid meets the M2 level rating and the wireless phone meets the M3 level
rating, the sum of the two values equal M5. This should provide the hearing aid user with “normal usage”
while using their hearing aid with the particular wireless phone. “Normal usage” in this context is defined as
a signal quality that is acceptable for normal operation.
The M mark is intended to be synonymous with the U mark. The T mark is intended to be synonymous with
the UT mark. The M and T marks are recommended by the Alliance for Telecommunications Industries
Solutions (ATIS). The U and UT marks are referenced in Section 20.19 of the FCC Rules. The HAC rating and
measurement procedure are described in the American National Standards Institute (ANSI) C63.19 standard.

THIS MODEL DEVICE MEETS THE GOVERNMENT’S REQUIREMENTS FOR EXPOSURE TO RADIO WAVES.
For body worn operation, this phone has been tested and meets the FCC RF exposure guidelines when
used with the HTC Corporation accessories supplied or designated for this product. Use of other
acccessoies may not ensure compliance with the FCC RF exposure guidelines.
Your wireless mobile CDMA phone is a radio transmitter and receiver. It is designed and manufactured not
to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal
Communications Commission of the U.S. Government. These limits are part of comprehensive guidelines
and establish permitted levels of RF energy for the general population. The guidelines are based on the
safety standards previously set by both U.S. and international standards bodies:
ⅷ American National Standards Institute (ANSI) IEEE. C95.1-1992.
ⅷ National Council on Radiation Protection and Measurement (NCRP). Report 86. 1986.
ⅷ International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1996.
ⅷ Ministry of Health (Canada), Safety Code 6. The standards include a substantial safety margin designed to
assure the safety of all persons, regardless of age and health.
The exposure standard for wireless mobile CDMA phone employs a unit of measurement known as the
Specific Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg*.
