5.0 FCC Compliance Notice
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and if not
installed and used in accordance with the instructions, may cause
harmful interference 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, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the
receiver.
• Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for
help.
6.0 FCC Phone Connection Notice To Users
This control complies with Part 68 of the FCC rules.
On the top of the PCB is a label that contains, among other informa-
tion, the FCC Registration Number and the Ringer Equivalence
Number (REN) for this equipment. You must, upon request, provide
this information to your local telephone company.
The REN is useful to determine the quantity of devices that you may
connect to your telephone line and still have all of those devices
ring when your telephone number is called. In most, but not all
areas, the sum of the REN's of all devices connected to one line
should not exceed five (5.0). To be certain of the number of devices
that you may connect to your line, you may want to contact your
local telephone company to determine the maximum REN for your
local calling area.
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 tele-
phone company may make changes in its facilities, equipment,
operations, or 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 equip-
ment 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 manufacturer and not by 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
accidents or acts of God cause an interruption in telephone service.
7.0 Canadian Department 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 telecommu-
nications 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 com-
pany 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.
Caution: Users should not attempt to make such connections
themselves, but should contact the appropriate
electric inspection authority, or electrician, as appro-
priate.
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 DS7420i 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.]
The Sounder Test is activated by entering a PIN followed by [#] [8]
