Le présent émetteur radio (TRM-900-TT) a été approuvé par Industrie 
Canada pour fonctionner avec les types d’antenne énumérés la Figure 30 
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.

Product Labeling

The end product must be labeled to meet the FCC and IC product label 
requirements. It must have the below or similar text:
Contains FCC ID: OJMTRM900TTA / IC: 5840A-TRM900TTA
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, this radio transmitter 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 TRM-900-TT radio transmitter has been approved by the FCC and 
Industry Canada to operate with the antenna types listed in Figure 30 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.
