Label and text information type should be large enough to be legible and consistent with the

dimensions of the equipment and the label. The type size is not required to be larger than

eight points.

Comments

The OEM should have their device tested by a qualified test house to verify compliance with
FCC Part 15 Subpart B limits for unintentional radiators.

Any modifications to the GEM 2 module could void the OEM’s authority to operate the
equipment.

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 not cause harmful interference to radio or

television reception, which can be determined by turning the equipment off and on, the user

is encouraged to correct the interference by one or more of the following measures:

Re‐orient or relocate the receiving antenna

Increase the separation between the equipment and the receiver

Connect the equipment to an outlet on a circuit that is different from that to which
the receiver is connected.

Consult the dealer or an experienced radio/TV technician for help.

FCC Warning:

“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 HARMFUL INTERFERENCE, AND (2) THIS
DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT

MAY CAUSE UNDESIRED OPERATION.

Industry Canada (IC) Warning:

This device complies with 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.

French equivalent:

Le présent appareil est conforme aux CNR d'Industrie Canada applicable 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
