Federal Communication Commission Interference Statement
This device complies with part 15 of the FCC Rules and Industry Canada license exempt RSS
standard(s). Operation is subject to the following three 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. (3) Any changes or modifications not expressly approved by
Motorola Solutions may void the user's authority to operate this device.
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 and complies with Canadian ICES-003. 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 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.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
For Canada: Operations in the 5.15-5.25GHz band are restricted to indoor usage only.
This device meets all the other requirements specified in Part 15E, Section 15.407 of the FCC Rules.
Wireless Device Country Approvals
Regulatory markings, subject to certification, are applied to the device signifying that the radio(s) is/are
approved for use in the US. Operation of the device without regulatory approval is illegal.
FOR COUNTRY CODE SELECTION USAGE (WLAN DEVICES)
NOTICE: The country code selection is for non-US model only and is not available to all US
model. Per FCC regulation, all WiFi product marketed in US must fixed to US operation
channels only.

About This Manual
Industry Canada WLAN statement
CAUTION:
(i) the device for operation in the band 5150-5250 MHz is only for indoor use to reduce the
potential for harmful interference to co-channel mobile satellite systems;
(ii) the maximum antenna gain permitted for devices in the bands 5250-5350 MHz and
5470-5725 MHz shall be such that the equipment still complies with the e.i.r.p. limit;
(iii) the maximum antenna gain permitted for devices in the band 5725-5850 MHz shall be such
that the equipment still complies with the e.i.r.p. limits specified for point-to-point and non-pointto-point operation as appropriate; and
(iv) the worst-case tilt angle(s) necessary to remain compliant with the e.i.r.p. elevation mask
requirement set forth in Section 6.2.2(3) shall be clearly indicated.
(v) Users should also be advised that high-power radars are allocated as primary users (i.e.
priority users) of the bands 5250-5350 MHz and 5650-5850 MHz and that these radars could
cause interference and/or damage to LE-LAN devices.
Use with Hearing Aids
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 some 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. Consult your service provider or the manufacturer of this phone for
information on hearing aid compatibility. If you have questions about return or exchange policies,
consult your service provider or the manufacturer of this phone.
To determine the compatibility of a WD and a particular hearing aid, simply add the numerical part of
the hearing aid category (e.g. M2/T2=2) with the numerical part of the WD emission rating (e.g., M3=3)
to arrive at the system classification for this particular combination of WD and hearing aid. A sum of 5
would indicate that the WD and hearing aid would provide normal use, and a sum of 6 or greater would
indicate that the WD and hearing aid would provide excellent performance. A category sum of less
than 4 would likely result in a performance that is judged unacceptable by the hearing aid user.
WHAT IS HEARING AID COMPATIBILITY?
The Federal Communications Commission has implemented rules and a rating system designed to
enable people who wear hearing aids to more effectively use these wireless telecommunications
devices. The standard for compatibility of digital wireless phones with hearing aids is set forth in
American National Standard Institute (ANSI) standard C63.19. There are two sets of ANSI standards
with ratings from one to four (four being the best rating): an “M” rating for reduced interference making
it easier to hear conversations on the phone when using the hearing aid microphone, and a “T” rating
that enables the phone to be used with hearing aids operating in the telecoil mode thus reducing
unwanted background noise.
HOW WILL I KNOW WHICH WIRELESS PHONES ARE HEARING AID COMPATIBLE?
The Hearing Aid Compatibility rating is displayed on the wireless phone box.
A phone is considered Hearing Aid Compatible for acoustic coupling (microphone mode) if it has an
“M3” or “M4” rating. A digital wireless phone is considered Hearing Aid Compatible for inductive
coupling (telecoil mode) if it has a “T3” or “T4” rating.
The tested M-Rating and T-Rating for this device (FCC/IC ID: AZ489FT7104/109U-89FT7104) are M4
and T3.
HOW WILL I KNOW IF MY HEARING AID WILL WORK WITH A PARTICULAR DIGITAL WIRELESS
PHONE?
You’ll want to try a number of wireless phones so that you can decide which works the best with your
hearing aids. You may also want to talk with your hearing aid professional about the extent to which
22
MN005019A01-B
About This Manual
your hearing aids are immune to interference, if they have wireless phone shielding, and whether your
hearing aid has a HAC rating.
Versions
This guide covers various software configurations and references made to operating system or
software versions.
For the operating system version, software build number, and the kernel version you can go to
Settings → About phone → Phone status.
