SAFETY AND REGULATORY INFORMATION
HAC RATING
The FCC has created a rating system for cellular phones
regarding their HAC-related performance. This rating
helps consumers with hearing disabilities to nd phones
that work well with their hearing aid devices. The HAC
rating and measurement procedure are described in the
American National Standards Institute (ANSI C63.19-
2011) contains two rating standards: an “M” rating from
1 to 4 for hearing aids operating in microphone mode,
and a “T” rating from 1 to 4 for hearing aids operating in
telecoil mode. M-Rating stands for Microphone rating
and indicates the amount of reduction of RF interference
between the telephone and the hearing aid in acoustic
coupling mode (also called microphone mode). Phones
rated M3 or M4 meet FCC requirements and generate
less interference to hearing devices set in microphone
mode. T-Rating stands for telecoil rating and represents
inductive coupling with hearing aids that are operating
in telecoil mode. A telecoil is a small piece of tightly
wrapped wire, built into some hearing aids. While the
microphone of a hearing aid picks up all sounds, the
telecoil only picks up an electromagnetic signal from the
telephone. Thus, users of telecoil-equipped hearing aids
are able to communicate over the telephone without the
amplication of unwanted background noise.
Phones rated T3 or T4 meet FCC requirements and
generate less interference to hearing devices set in
telecoil mode. A combination of M-rating and T-rating
denes the nal HAC rating and is a deciding factor
in selecting cellular phones for people with hearing
problems. A HAC compliant phone could be rated:
• M3/T3
• M3/T4
• M4/T3
• M4/T4
Its resistance to interference. The best way to evaluate
the suitability of the phone is to try it with the intended
hearing aid device.
The model XP3900 have been tested for hearing aid
device compatibility and complies with the Federal
Communications Commission (FCC) requirements.
These devices are rated M4/T4.
RADIO FREQUENCY ENERGY
This device meets the government’s requirements for
exposure to radio waves.
This device 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.
The exposure standard for wireless device employs a
unit of measurement known as the Specic Absorption
Rate, or SAR. The SAR limit set by the FCC is 1.6W/
kg. *Tests for SAR are conducted using standard
operating positions accepted by the FCC with the device
transmitting at its highest certied power level in all tested
frequency bands. Although the SAR is determined at the
highest certied power level, the actual SAR level of the
device while operating can be well below the maximum
value. This is because the device is designed to operate
at multiple power levels so as to use only the poser
required to reach the network. In general, the closer you
are to a wireless base station antenna, the lower the
power output.
The highest SAR value for the model device XP3900
(Type number P14303 & P14403) as reported to the FCC:
• When tested for use at the ear is 0.537 W/kg, and
• When worn on the body, as described in this user
guide, is 0.837 W/kg (Body-worn measurements
differ among device models, depending upon
available accessories and FCC requirements.).
• When device is set as Hotspot mode as described
in this user guide, is 1.057 W/kg. While there may
be differences between the SAR levels of various
devices and at various positions, they all meet the
government requirement.
• When device is set as Simultaneous Transmission
mode, is 1.490 W/kg.
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 le with the
FCC and can be found under the Display Grant section
of www.fcc.gov/oet/ea/fccid after searching on FCC ID:
WYPP14303.
For body worn operation, this device has been tested
and meets the FCC RF exposure guidelines for use with
an accessory that contains no metal and be positioned
a minimum of 15 mm from the body. When the device is
set to hotspot mode, please use it at least 10 mm away
from your body. Use of other accessories may not ensure
compliance with FCC RF exposure guidelines. If you do
not use a body-worn accessory and are not holding the
device at the ear, position the handset a minimum of 0
cm from your body when the device is switched on.
