necessary to correct the interference.

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 numériques de classe A prescrites dans le Règlement sur le

brouillage radioélectrique publié par Industrie Canada.
