FCC Compliance for
Part 15B/Part 15C
This device complies with part 15 of the
FCC Rules. Operation is subject to the
following two conditions: (1) This device
may not cause harmful interference, and
(2) this device must accept any interference
received, including interference that may
cause undesired operation.
Caution: Changes or modifications not
expressly approved by the manufacturer
could void the user’s authority to operate
the equipment.
Note: This equipment has been tested and
found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide
reasonable protection against harmful
interference in a residential installation.
This equipment generates, uses, and can
radiate radio frequency energy and, if not
installed and used in accordance with the
instructions, may cause harmful interference
to radio communications. However, there
is no guarantee that interference will not
occur in a particular installation. If this
equipment does cause harmful interference
to radio or television reception, which can
be determined by turning the equipment
off and on, the user is encouraged to try to
correct the interference by one or more of
the following measures:
• Reorient or relocate the receiving
antenna.
• Increase the separation between the
equipment and receiver.
• Connect the equipment into an outlet on
a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced
radio/TV technician for help.
NONE PART 15B/PART 15C is as below
FCC Compliance
This device complies with part 15 of the
FCC Rules. Operation is subject to the
condition that this device does not cause
harmful interference.
Caution: Changes or modifications not
expressly approved by the manufacturer
could void the user’s authority to operate
the equipment.
M-Ratings: Phones rated M3 or M4 meet
FCC requirements and are likely to generate
less interference with hearing devices than
phones that are not labeled. M4 is the
better/higher of the two ratings.
T-Ratings: Phones rated T3 or T4 meet
FCC requirements and are likely to be more
usable with a hearing device’s telecoil
(“T Switch” or “Telephone Switch”) than
unrated phones. T4 is the better/higher of
the two ratings. (Note that not all hearing
devices contain telecoils.)
The more immune your hearing aid device
is, the less likely you are to experience
interference noise from your wireless phone.
Hearing aid devices should have ratings
similar to those of phones. Ask your hearing
health-care professional for the rating of
your hearing aid.
Hearing devices may also be measured
for immunity to this type of interference.
Your hearing device manufacturer or hearing
health professional may help you find results
for your hearing device. The more immune
your hearing aid is, the less likely you are
to experience interference noise from
wireless devices.
For additional information about the
FCC’s actions with regard to hearing aid
compatible wireless devices and other
steps the FCC has taken to ensure that
Using Your Phone with
a Hearing Aid Device
Your F160 device is compliant with the FCC
and IC Hearing Aid Compatibility (HAC)
requirements.
When some wireless phones are used
near some hearing devices (hearing aids
and cochlear implants), users may detect a
buzzing, humming, or whining noise. Some
hearing devices are more immune than
others to this interference noise, and phones
also vary in the amount of interference they
generate. The wireless telephone industry
has developed ratings for some of their
mobile phones to assist hearing-device users
in finding phones that may be compatible
with their hearing devices. Not all phones
have been rated. Phones that have been
rated have a label on the box. Your F160
has been tested for hearing aid device
compatibility and has an M[4] and/or
T[4] rating.
These ratings are not guaranteed. Results
will vary, depending on the level of immunity
of your hearing device and the degree of
your hearing loss. If your hearing device
happens to be vulnerable to interference,
you may not be able to use a rated phone
successfully. Trying out the phone with your
hearing device is the best way to evaluate it
for your personal needs.
