To comply with state tariffs, the telephone company 
must be given notification prior to connection. In 
some states, the state public utility commission, pub-
lic service commission or corporation commission 
must give prior approval of connection.

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.

Your equipment has been tested and found to 
comply with the limits of a Class B digital device, 
pursuant to Part 15 of FCC rules. These limits are 
designed to provide reasonable protection against 
harmful interference in residential installation.

This equipment generates, uses and can radiate radio 
frequency energy and, if not installed and used in ac-
cordance with the instructions, may cause harmful in-
terference 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, you are encouraged to try to correct the 
interference by one of the following measures:

1.  Where it can be done safely, reorient the  
 

receiving television or radio antenna.

2.  To the extent possible, relocate the television,  
 

radio or other receiver with respect to the  

 

telephone equipment. (This increases the  

 

separation between the telephone equipment  

 

and the receiver.)

3.  Connect the telephone equipment into an  

 

 

outlet on a circuit different from that to which    

 

the television, radio, or other receiver is  

 

connected.

4.  Consult the dealer or an experienced Radio/ 

 

 

TV Technician for help.   

CAUTION: Changes or modifications not ex-
pressly approved by the manufacturer responsible for 
compliance could void the user’s authority to oper-
ate the equipment.

This product meets the applicable Industry Canada 
technical specifications.

Before installing this equipment, users should ensure 
that it is permissible to be connected to the facili-
ties of the local telecommunications company. The 
equipment must also be installed using an acceptable 
method of connection. In some cases, the company’s 
inside wiring associated with a single line individual 
service may be extended by means of a certified 
connector assembly (telephone extension cord). The 
customer should be aware that compliance with the 
above conditions may not prevent degradation of 
service in some situations. Repairs to certified equip-
ment should be made by an authorized Canadian 
maintenance facility 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 util-
ity, telephone lines and internal metallic water pipe 
system, if present, are connected together. This pre-
caution may be particularly important in rural areas.
