IC Statement 

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 device complies with Industry Canada licence-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. This device complies 
with  Industry  Canada  radiation  exposure  limits  set  forth  for  general  population.  This  device  must  not  be  co-located  or 
operating in conjunction with any other antenna or transmitter. 
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  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'e

n  compromettre  le  fonctionnement.  Le  présent  appareil  est  conforme  aux  niveaux  limites  d’exigences 

d’exposition RF pour la population globale définies par Industrie Canada. L’appareil ne doit pas être installé à proximité ou 
être utilisé en conjonction avec une autre antenne ou un autre émetteur.  

 
FCC statement 

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. 
(a) (5) When the device is so small or for such use that it is not practicable to place the statement specified under paragraph 
(a) of this section on it, the information required by this paragraph shall be placed in a prominent location in the instruction 
manual or pamphlet supplied to the user or, alternatively, shall be placed on the container in which the device is marketed. 
However, the FCC identifier or the unique identifier, as appropriate, must be displayed on the device.  
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 instruction, 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 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 circuit different from that to 
which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help.  
This device complies with FCC radiation exposure limits set forth for general population. This device must not be co-located 
or operating in conjunction with any other antenna or transmitter.
