 Changes  or  modifications  not  expressly  approved  by  the  party  responsible  for  compliance  could  void  the  user’s 
authority to operate the equipment. 
 
 This digital apparatus does not exceed the Class A limits for radio noise emission from digital apparatus set out in 
the Radio Interference Regulation of Industry Canada. 
 
 Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils
