Government Certification
Attached to the telephone is a label for the Australian Communications Authority. This identifies
equipment certifications indicating the WRT-A series telephones meet certain telecommunications
network protective, operational and safety requirements. This agency does 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.
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.

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.)
