Regulatory Information and Certifications

1.1 Antenna Related User Notification

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.

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.

WiFi Connection J2

Note: Only this antenna or those with the same specification may be used with the WiFi connection.

Note: Only this antenna or those with the same specification may be used with the Cellular connection.
The device contains Cinterion’s HC25 (FCC ID: QIPHC25) and the module grants allows an antenna with
these specifications.

This radio transmitter has been approved by Industry Canada to operate with the antenna types listed in
the table above 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. The required antenna impedance
is 50 ohms.

Document Number 90001271

Le présent émetteur radio a été approuvé par Industrie Canada pour fonctionner avec les types
d'antenne énumérés ci-dessous 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.

FCC/IC notes regarding Radio Interference

This device complies with Part 15 of the FCC Rules and with license-exempt RSS standard(s) of Industry
Canada. 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 of the device.

Cet appareil se plie à la Partie 15 des Règles de FCC et exemptes de licence RSS norme(s) d'Industrie
Canada. L'opération est soumise aux deux conditions suivantes : (1) cet artifice peut ne pas provoquer
l'interférence malfaisante et (2) cet appareil doit accepter n'importe quelle interférence reçue, en
incluant l'interférence qui peut provoquer l'opération indésirable de l'appareil.

1.2

Radio Frequency radiation exposure Information:

This equipment complies with FCC and IC radiation exposure limits set forth for an uncontrolled
environment when installed and operated so that a minimum distance of 20 cm between the radiator
and the body of persons is maintained

Cet équipement est conforme à la radioexposition de la FCC établies pour un environnement non
contrôlé lorsqu'il est installé et exploité de telle sorte qu'une distance minimale de 20 cm entre le
radiateur et le corps de personnes est maintenue

1.3

Unauthorized Product Changes

Changes or modifications to this equipment not expressly approved by Digi may void the user's authority
to operate this equipment.

Tout changement ou modification apportés à ce dispositif n'étant pas expressément approuvés par Digi
peut priver l'utilisateur de mettre en œuvre cet équipement.
