About the Modem

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 modem jack of this equipment complies with Sub-part F of Part 68 of FCC
rules.

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

(5.0).

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 areas.

If the terminal equipment causes harm to the telephone network, the telephone
company will notify you in advance that temporary discontinuance of service may
be required. But if advance notice isn’t practical, the telephone company will notify
the customer as soon as possible. Also, you will be advised of your right to file a
complaint with the FCC if you believe it necessary.

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.

each transmitted page or on the first page of the transmission, the date and time it
is sent and an identification of the business or other entity, or other individual
sending the message and the telephone number of the sending machine or such
business, other entity, or individual. (The telephone number provided may not be a

About Modem

The Industry Canada label identifies certified equipment.
This certification means that the equipment meet 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 equipmerit, 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.

CAUTION Users should not attempt to make such connections themselves, but

should contact the appropriate electric inspection authority, or electrician, as
appropriate.

“The Ringer Eqhvalence Number (REN) 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 Ringer
Equivalence Number of all the devices does not exceed 5.”
