This equipment may not be used on coin service provided by the
telephone company. This control should not be connected to party
lines.
Should this equipment cause harm to the telephone network, the
telephone company may discontinue your service temporarily. If
possible, they will notify you in advance. But if advanced notice isn’t
practical, you will be notified as soon as possible. You will be informed
of your right to file a complaint with the FCC. The telephone company

procedures that could affect the proper functioning of your equipment.
If they do, you will be notified in advance to give you an opportunity
to maintain uninterrupted telephone service.
If you experience trouble with this equipment, please contact the
manufacturer for information on obtaining service or repairs.
The telephone company may ask that you disconnect this equipment
from the network until the problem has been corrected or until you
are sure that the equipment is not malfunctioning. The repairs to
this equipment must be made by the manufacturer and not the user.
To guard against accidental disconnection, there is ample room to
mount the Telco jack to the inside of the Control cabinet.
The operation of this Control may also be affected if events such as

6.18 Canadian Dept. of Communications
General Installation Requirements: Notice: The Canadian
Department of Communications label identifies certified equipment.
This certification means that the equipment meets certain
telecommunications network, protective, operational, and safety
requirements. 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. 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 equipment 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 utility, telephone lines, and internal
metallic water pipe system, if present, are connected together. This
precaution may be particularly important in rural areas.
Users should not attempt to make such connections
themselves, but should contact the appropriate electric
inspection authority, or electrician, as appropriate.
Terminal Requirements: The Load Number (LN) assigned to each
terminal device denotes the percentage of the total load to be
connected to a telephone loop which is used by the device, to prevent
overloading. The 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. The
Load Number of the DS7400Xi is 2.
RFI Requirements: This Class A digital apparatus meets all
requirements of the Canadian Interference-Causing Equipment
Regulations. [Cet appareil numerique de la classe A respecte toutes
les exigences du Reglement sur le material broilleur du Canada.]
6.19 For Installations in New Zealand
Two-wire Connection:
The operation of this equipment on the same line as telephones or
other equipment with audible warning devices or automatic ring
detectors will give rise to bell tinkle or noise and may cause false
tripping of the ring detector. Should such problems occur, the user
is not to contact Telecom Faults Service.
