Notice
The Industry Canada label identifies certified equipment. This certification means that the equipment meets telecommu-
nications network protective, operational and safety requirements as prescribed in the appropriate Technical Equipment
Technical Requirements document(s). The Department does not guarantee the equipment will operate to the user’s satis-
faction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local
telecommunications company. The equipment must also be installed using an acceptable method of connection. The
customer should be aware that compliance with the above conditions may not prevent degradation of service in some
situations.
Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or
alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company
cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections at the power utility, telephone lines
and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important
in rural areas.
Caution:
Users should not attempt to make such connections themselves, but should contact the appropri-
ate electrical inspection authority, or electrician, as appropriate.
