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

electrical inspection authority or electrician. 
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 Australian Communications Authority registration number. The 
local telephone company may request disconnection of the telephone where alterations or malfunctions 
affect the telephone’s performance. 
ACA Rules and Ringer Equivalence Number 
This equipment complies with the regulation AS/ACIF S002:2001 Australian Standard Analogue 
internetworking and non-interference requirements for customer equipment for connection to public 
switched telephone networks.  On the side of this equipment is a label that contains, among other 
information, the ACA 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 three.  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.

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.)
