Regulatory Notices:

3.1

United States

3.1.1

Notice applicable to EVMs not FCC-Approved:

FCC NOTICE:

This kit is designed to allow product developers to evaluate electronic components, circuitry, or software

associated with the kit to determine whether to incorporate such items in a finished product and software developers to write
software applications for use with the end product. This kit is not a finished product and when assembled may not be resold or
otherwise marketed unless all required FCC equipment authorizations are first obtained. Operation is subject to the condition
that this product not cause harmful interference to licensed radio stations and that this product accept harmful interference.
Unless the assembled kit is designed to operate under part 15, part 18 or part 95 of this chapter, the operator of the kit must
operate under the authority of an FCC license holder or must secure an experimental authorization under part 5 of this chapter.

3.1.2

For EVMs annotated as FCC – FEDERAL COMMUNICATIONS COMMISSION Part 15 Compliant:

CAUTION

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.

Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to
operate the equipment.

FCC Interference Statement for Class A EVM devices

NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to
correct the interference at his own expense.

FCC Interference Statement for Class B EVM devices

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.

3.2

Canada

3.2.1

For EVMs issued with an Industry Canada Certificate of Conformance to RSS-210 or RSS-247

Concerning EVMs Including Radio Transmitters:

This device complies with Industry Canada license-exempt RSSs. 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.

Concernant les EVMs avec appareils radio:

Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation
est autorisée aux deux conditions suivantes: (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit
accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.

Concerning EVMs Including Detachable Antennas:

Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser)
gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type
and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for
successful communication. This radio transmitter has been approved by Industry Canada to operate with the antenna types
listed in the user guide with the maximum permissible gain and required antenna impedance for each antenna type indicated.
Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited
for use with this device.
