User Guide v
Accessories
Use only Kyocera-approved accessories with
Kyocera phones. Use of any unauthorized
accessories may be dangerous and will invalidate
the phone warranty if said accessories cause
damage or a defect to the phone.
Radio Frequency (RF) energy
Your telephone is a radio transmitter and receiver.
When it is on, it receives and sends out RF energy.
Your service provider’s network controls the power
of the RF signal. This power level can range from
0.006 to 0.6 watts.
In August 1996, the U.S. Federal Communications
Commission (FCC) adopted RF exposure
guidelines with safety levels for hand-held
wireless phones. These guidelines are
consistent with the safety standards previously
set by both U.S. and international standards
bodies in the following reports:
• ANSI C95.1 (American National Standards
Institute, 1992)
• NCRP Report 86 (National Council
on Radiation Protection and
Measurements, 1986)
• ICNIRP (International Commission on
Non-Ionizing Radiation Protection, 1996)
Your phone complies with the standards set by
these reports and the FCC guidelines.
E911 mandates
Where service is available, this handset complies
with the Phase I and Phase II E911 Mandates
issued by the FCC.
Hearing Aid Compatibility (HAC) Features
This Virgin Mobile phone has received a HAC
performance rating (designated by the letter M
followed by a number). The rating for this phone is
identified on the outside of this phone’s original
packaging. While there is no guarantee, digital
wireless phones that receive a minimum of an M3
rating should provide acceptable performance with
most hearing aids. Hearing loss and hearing aids
are highly individualized, however, so optimal
performance cannot be guaranteed. Other factors,
such as type of hearing aid device or degree of
hearing loss, also can affect a phone’s
performance for a particular user.
Hearing Aids and Wireless Phones
A hearing aid uses a microphone to collect and
convert sound waves to electrical signals. The
hearing aid then amplifies and converts the
electrical signals back to audible sounds for the
hearing aid user to hear. Radio Frequency (RF)
emissions generated by digital wireless phones
often interfere with the operation of a hearing aid’s
microphone, distorting the amplified audible sound.
In addition, hearing aid microphones tend to collect
ambient noise and amplify these sounds,
interfering with the desired audio transmission.
ANSI Standard
To diminish interference between wireless phones
and hearing aids, the FCC requires wireless
carriers to offer phones that meet the American
National Standards Institute (ANSI) C63.19
standard for reduced RF emissions.
Wireless phones that comply with the FCC’s
hearing aid compatibility (HAC) regulations must
receive a minimum rating of “M3” for RF
emissions under the ANSI C63.19 standard. The
“M” rating refers to the phone’s RF emissions level
for use with hearing aids operating in the
microphone setting.
The higher the phone’s “M” rating, the more
likely the phone is compatible with a hearing aid
operating in the microphone setting. Hearing
aids also have ratings similar to wireless phones.
Most newer hearing aid models receive at least
an M2 rating.
