Product Labeling
The end product containing the HUM-900-PRO-UFL or
HUM-900-PRO-CAS must be labeled to meet the FCC and IC product
label requirements. It must have the below or similar text:
Contains FCC ID: OJM900MCA / IC: 5840A-900MCA
The label must be permanently affixed to the product and readily visible to
the user. ‘‘Permanently affixed’’ means that the label is etched, engraved,
stamped, silkscreened, indelibly printed, or otherwise permanently marked
on a permanently attached part of the equipment or on a nameplate of
metal, plastic, or other material fastened to the equipment by welding,
riveting, or a permanent adhesive. The label must be designed to last
the expected lifetime of the equipment in the environment in which the
equipment may be operated and must not be readily detachable.
FCC RF Exposure Statement
To satisfy RF exposure requirements, this device and its antenna must
operate with a separation distance of at least 20cm from all persons and
must not be co-located or operating in conjunction with any other antenna
or transmitter.
Antenna Selection
Under FCC and Industry Canada regulations, the HUM-900-PRO-UFL and
HUM-900-PRO-CAS radio transmitters may only operate using an antenna
of a type and maximum (or lesser) gain approved for the transmitter by
the FCC and 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.
The HUM-900-PRO-UFL and HUM-900-PRO-CAS radio transmitters
have been approved by the FCC and Industry Canada to operate with the
antenna types listed in Figure 107 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.
Conformément à la réglementation d’Industrie Canada, le présent émetteur
radio peut fonctionner avec une antenne d’un type et d’un gain maximal
(ou inférieur) approuvé pour l’émetteur par Industrie Canada. Dans le but
de réduire les risques de brouillage radioélectrique à l’intention des autres
utilisateurs, il faut choisir le type d’antenne et son gain de sorte que la
puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l’intensité
nécessaire à l’établissement d’une communication satisfaisante.
Le présent émetteur radio (HUM-900-PRO-UFL, HUM-900-PRO-CAS)
a été approuvé par Industrie Canada pour fonctionner avec les types
d’antenne énumérés la Figure 107 et ayant un gain admissible maximal
et l’impédance requise pour chaque type d’antenne. Les types d’antenne
non inclus dans cette liste, ou dont le gain est supérieur au gain maximal
indiqué, sont strictement interdits pour l’exploitation de l’émetteur.
