FCC Hearing Aid Compatibility (HAC)
Regulations for Wireless Devices
The FCC has adopted rules to ensure reasonable
access to telecommunications services for persons
with hearing disabilities. As part of this effort, the
industry uses a rating system for wireless phones to
help hearing device users find phones that may be
compatible with their hearing devices (hearing aids
and cochlear implants). This hearing aid compatibility

Getting the Best Hearing Device Experience
With Your Phone
To further minimize interference:
• Set the phone’s display and keypad backlight
settings to ensure the minimum time interval.
• Position the phone so the internal antenna is farthest
from your hearing aid.
• Move the phone around to find the point with least
interference.
Caring for the Battery
Protecting Your Battery
The guidelines listed below help you get the most out
of your battery’s performance.
• Recently there have been some public reports of
wireless phone batteries overheating, catching
fire, or exploding. It appears that many, if not all, of
these reports involve counterfeit or inexpensive,
aftermarket-brand batteries with unknown or
questionable manufacturing standards. Sprint is
not aware of similar problems with Sprint phones
resulting from the proper use of batteries and
accessories approved by Sprint or the manufacturer
of your phone. Use only Sprint-approved or
manufacturer-approved batteries and accessories
found at Sprint Stores or through your phone’s
manufacturer, or call 1-866-866-7509 to order.
They’re also available at sprint.com/accessories.
Buying the right batteries and accessories is the
best way to ensure they’re genuine and safe.
• In order to avoid damage, charge the battery only in
temperatures that range from 32° F to 104° F (0° C
to 40° C).
• Don’t use the battery charger in direct sunlight or in
high humidity areas, such as the bathroom.
• Never dispose of the battery by incineration.
• Keep the metal contacts on top of the battery clean.
(HAC) rating system is described in the American
National Standards Institute (ANSI) C63.19 standard
and includes the following ratings:
M-Ratings: Used for phones that use acoustic
coupling with hearing devices that are not operating
in telecoil mode. Phones rated M3 or M4 meet FCC
HAC requirements and are less likely to generate
interference with hearing devices than phones with
lower ratings. M4 is the better/higher of the two ratings.
Your HTC 8XT is rated M4.
T-Ratings: Used for phones that use inductive coupling
with hearing devices operating in telecoil mode.
Phones rated T3 or T4 meet FCC HAC requirements
and are more likely to be usable with a hearing aid’s
telecoil than phones that are not rated. T4 is the better/
higher of the two ratings. Your HTC 8XT is rated T4.
This phone has been tested and rated for use with
hearing aids for some of the wireless technologies
that it uses. However, there may be newer wireless
technologies used in this phone that have not been
tested yet for use with hearing aids. It is important to
try the different features of this phone thoroughly and in
different locations, using your hearing aid or cochlear
implant, to determine if you hear any interfering noise.
HAC ratings are not guarantees. Results will vary
depending on the user’s hearing device and hearing
loss. Trying out a phone with your hearing device is the
best way to evaluate it for your personal needs.
Hearing aid devices may receive HAC ratings similar to
the HAC ratings that measure immunity to interference
noise from wireless phones. Ask your hearing
healthcare professional for the rating of your hearing
aid.
Sprint further suggests you experiment with multiple
phones while in the store to find the one that works best
with your hearing aid device. Should you experience
interference or find the quality of service unsatisfactory
after purchasing your phone, promptly return it to the
store within 14 days of purchase. (A restocking fee may
be applied to exchanges. Visit sprint.com/returns for
details.) You can find more information about hearing
aid compatibility at: fcc.gov, fda.gov, and

developed this updated standard after reviewing
the available body of research. In 1993, the Federal
Communications Commission (FCC) adopted this
updated standard in a regulation. In August 1996, the
FCC adopted hybrid standard consisting of the existing
ANSI/IEEE standard and the guidelines published
by the National Council of Radiation Protection and
Measurements (NCRP).
Body-Worn Operation
To maintain compliance with FCC RF exposure
guidelines, if you wear a handset on your body, use
a Sprint-supplied or Sprint-approved carrying case,
holster or other body-worn accessory. If you do not
use a body-worn accessory, ensure the antenna is at
least 7/24 inch (1.0 centimeters) from your body when
transmitting. Use of non-Sprint-approved accessories
may violate FCC RF exposure guidelines.
For more information about RF exposure, visit the FCC
website at fcc.gov.
FCC RF Radiation Exposure Statement
This equipment has been tested and found to comply
with co-location compliance requirements for built-in
Bluetooth and WLAN. This equipment must not be
co-located or operated in conjunction with any other
antenna or transmitter.
Specific Absorption Rates (SAR) for
Wireless Phones
The FCC’s RF exposure standards employ a unit of
measurement known as the Specific Absorption Rate
(SAR).
The SAR value of a phone is the result of an extensive
testing, measuring and calculation process. It does
not represent how much RF the phone emits. All
phone models are tested at their highest value in strict
laboratory settings. But when in operation, the SAR
of a phone can be substantially less than the level
reported to the FCC. This is because of a variety of
factors including its proximity to a base station antenna,
