Government Certification 
Attached to the telephone are labels for Industry Canada and the United States Federal Communications Commission. These identify 
equipment certifications indicating the 60 and 70 series telephones meet certain telecommunications network protective, operational 
and safety requirements. These agencies do not guarantee the equipment will operate to the user's satisfaction. 
Before installing this telephone equipment, users should ensure it is permissible to connect the equipment to facilities of the local 
telecommunications company.  
Equipment must be installed using acceptable connection methods. In some cases, the telephone users inside wiring, associated with 
a single line service, may be extended by a certified connector assembly (telephone extension cord). The customer should be aware 
that in some situations compliance with the above conditions may not prevent degradation of service. 
Repairs to certified equipment should be made by a supplier designated authorized maintenance facility. 
For their own protection users should ensure the electrical ground connections of the power utility, telephone lines and internal 
metallic water pipe systems, if present, are connected. This precaution may be particularly important in rural areas. 
CAUTION:  Users should not attempt to make ground connections, but should contact the appropriate electrical inspection authority 
or electrician. 
Load Number (LN) 
The Load Number (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop 
used by the device.  Termination on a loop may consist of any combination of devices subject only to the requirement that the total of 
the Load Numbers of all the devices does not exceed 100. 
Notification to Telephone Company 
Upon request, the customer must notify the telephone company of the particular line to which the connection will be made and provide 
the Industry Canada or FCC registration number. The local telephone company may request disconnection of the telephone where 
alterations or malfunctions affect the telephone’s performance. 
United States Federal Communications Commission 
This equipment generates, uses and can radiate radio frequency energy, and if not installed and used in accordance with the 
instruction manual, may cause interference to radio communications.  It has been tested and found to comply with the limits for Class 
A computing device pursuant to Subpart J of Part 15 of FCC rules, which are designed to provide reasonable protection against such 
interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause 
interference in which case the user, at his own expense, will be required to take whatever measures may be required to correct the 
interference. 
Interference 
There is no guarantee that interference will not occur in a particular installation. If interference to radio or television reception from this 
equipment is suspected, proceed as follows: 
  
1. 
Unplug the set, check for the interference. 
  
2. 
Re-orient the receiving antenna. 
  
3. 
Relocate the set with respect to the receiver. 
  
4. 
Move the set away from the receiver. 
If necessary, consult the supplier or an experienced radio/television technician for additional suggestions. 
FCC Rules and Ringer Equivalence Number 
This equipment complies with Part 68 of the FCC Rules.  On the side of this equipment is a label that contains, among other 
information, the FCC registration number and ringer equivalence number (REN) for this equipment.  If requested, this information 
must be provided to the telephone company. 
The REN is used to determine the quantity of devices which may be connected to the telephone line.  Excessive RENs on the 
telephone line may result in the devices not ringing in response to an incoming call.  In most, but not all areas, the sum of the RENs 
should not exceed five.  To be certain of the number of devices that may be connected to the line, as determined by the total RENs, 
contact the telephone company to determine the maximum REN for the calling area. 
Service changes and Limitations 
The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect the operation of the 
equipment.  If this happens, the telephone company will provide advance notice in order for you to make the necessary modifications 
in order to maintain uninterrupted service. 
This equipment can not be used on public coin telephone service as provided by your telephone company.  Connection to party line 
service is subject to state tariffs (contact the state public utility commission, public service commission or corporate commission for 
information.)
