142 Appendix
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to generate less interference to
hearing devices than phones that are not labeled. M4 is the better/higher of the two ratings. RAPH500 is rated
M3.
Please power off the Bluetooth function while using hearing aid devices with your RAPH500.
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 accessories 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:
American National Standards Institute (ANSI) IEEE. C95.1-1992.
National Council on Radiation Protection and Measurement (NCRP). Report 86. 1986.
International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1996.
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.
This phone has been tested and meets the FCC RF exposure guidelines when used with an accessory that
contains no metal and that positions the handset a minimum of 1.5 cm from the body. The FCC has granted
an Equipment Authorization for this model device with all reported SAR levels evaluated as in compliance
with the FCC RF exposure guidelines. SAR information on this model device is on file with the FCC and can be
found under the Display Grant section of
https://fjallfoss.fcc.gov/oetcf/eas/reports/GenericSearch.cfm after
searching on FCC ID: NM8RAPH500. Additional information on Specific Absorption Rates (SAR) can be found
on the Cellular Telecommunications & Internet Association (CTIA) Web-site as http://www.phonefacts.net.
