MTXDOT-NA1 Series dot Arm Med Low Power RF Module
Limited Module approval:
This Limited Module approval with underlid mount omnidirectional folded dipole
antenna is only approved with the host device water meter valve application
tested. Any other use of this limited module will require a certification
review and testing applicable to the new application and a Class II Permissive
Change or other FCC/IC approval as applicable.
This antenna addition is based on testing of the listed antenna (See page 3 of
this addendum) with the host device in this Limited Module approval to the
following guidelines, and review of the test data and host design:
-
KDB 178919 D01 Section II, A, 3, (New antenna type) and FCC Part 15.203.
o Antenna type: Folded dipole antenna
o 2 dib gain (see page 3 and 4 of addendum) -
KDB 996369 D01 section III paragraph B: Limited the installation to a specific host or hosts, and KDB 996369 III, B.
-
KDB 447498 D04 Module Integration Guide, and KDB 447498 RF exposure compliance.
-
KDB 996369 D03 section 2 Limited Module Procedures, RF exposure.
Host testing and test mode:
For Host integrator, testing the device requires pairing with another device
and running at highest output power, or the use of test commands to set the
product under test to transmit at a high duty cycle and highest power setting.
The Limited Module transmitter is only approved for FCC/Canada transmitter
rules according to the FCC Grant /Canada Certification.
The host product manufacturer is responsible for compliance to any FCC/Canada
rules applicable to their host product.
FCC Grant – Notes for Limited Module Approval:
The OEM should follow all grant notes listed below. Otherwise, further testing
and device approvals may be necessary.
FCC Definitions
Portable: (§2.1093) — A portable device is defined as a transmitting device
designed to be used so that the radiating structure(s) of the device is/are
within 20 centimeters of the body of the user.
Mobile: (§2.1091) — A mobile device is defined as a transmitting device
designed to be used in other than fixed locations and to generally be used in
such a way that a separation distance of at least 20 centimeters is normally
maintained between the transmitter’s radiating structure(s) and the body of
the user or nearby persons.
This device is a mobile device with respect to RF exposure compliance. The
antenna(s) used for this transmitter must be installed to provide a separation
distance of at least 20 cm from all persons and must not be collocated or
operate in conjunction with any other antenna or transmitter except in
accordance with FCC multi- transmitter product guidelines. Installers and
end-users must be provided with specific information required to satisfy RF
exposure compliance for installations and final host devices. (See notes
below) Compliance of this device in all final host configurations is the
responsibility of the Grantee.
Notes:
- Host design configurations constituting a device for portable use (<20 cm from human body) requires separate FCC/IC approval.
- This Limited Module approval is only applicable to the host device water meter valve and omnidirectional folded dipole antenna application tested. Any other use will require additional testing and Class II Permissive Change approval. Host integration is subject to KDB 996369 and includes host integration and simultaneous transmissions if more than one intentional radiator.
Wireless notice for host integrator user manual:
This device complies with FCC radiation exposure limits set forth for an
uncontrolled environment and meets the FCC Radio Frequency (RF) Exposure
Guidelines. This transmitter must not be co-located or operate in conjunction
with any other antenna or transmitter except in accordance with FCC multi-
transmitter product guidelines. The antenna should be installed and operated
with a minimum distance of 20 cm between the radiator and your body.

The module label must be visible to users, or the host product label or
e-label must contain the following:
“Contains FCC ID: AU792U13A16858”
“Contains IC ID: 125A-0055”
Compliance Statement FCC and Canada:
o This device complies with Part 15 of the FCC Rules and Industry Canada
license-exempt RSS standard(s). Operation is subject to the following two
conditions: (1) this device may not cause interference, and (2) this device
must accept any interference, including interference that may cause undesired
operation of the device.
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.
CAN ICES-3 (B) / NMB-3 (B)
This Class B digital apparatus complies with Canadian ICES-003.
