safety requirements as prescribed in the appropriate Terminal Equipment Technical 
Requirements documents. The department does not guarantee the equipment will 
operate to the user's satisfaction. 

 
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 of 
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 appropriate electric inspection authority, or electrician, as appropriate.
