d) If this telephone equipment causes harm to
the telephone network, the telephone compa-
ny will notify you in advance that temporary
discontinuance of service may be required.
But if advance notice isn’t practical, the tele-
phone 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 is necessary.
Part 68 of FCC Rules Information
a) This equipment complies with Part 68 of
the FCC rules and the requirements adopted
by the ACTA. On the bottom of this equip-
ment is a label that contains, among other
information, a product identifier in the
format US:AAAEQ##TXXXX. If requested,
this number must be provided to the tele-
phone company.
e) The telephone company may make
changes in its facilities, equipment, opera-
tions 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
necessary modifications to maintain
uninterrupted service.
b) A plug and jack used to connect this
equipment to the premises wiring and
telephone network must comply with the
applicable FCC Part 68 rules and require-
ments adopted by the ACTA. A compliant
telephone cord and modular plug, RJ11C
USOC, is provided with this product. It is
designed to be connected to a compatible
modular jack that is also compliant. See
installation instructions for details.
f) If trouble is experienced with this telephone
equipment, for repair or warranty informa-
tion, please contact Clarity, 1-800-552-3368.
If the equipment is causing harm to the tele-
phone network, the telephone company may
request that you disconnect the equipment
until the problem is resolved.
c) The REN is used to determine the number
of devices that may be connected to a tele-
phone line. Excessive RENs on a telephone
line may result in the devices not ringing in
response to an incoming call. In most but not
all areas, the sum of RENs should not exceed
five (5.0). To be certain of the number of
devices that may be connected to a line, as
determined by the total RENs, contact the
local telephone company. For products
approved after July 23, 2001, the REN for
this product is part of the product identifier
that has the format US:AAAEQ##TXXXX.
The digits represented by ## are the REN
without a decimal point (e.g., 03 is a REN
of 0.3). For earlier products, the REN is
separately shown on the label.
g) This telephone equipment is not intended
to be repaired and it contains no repair-
able parts. Opening the equipment or
any attempt to perform repairs will void
the warranty. For service or repairs, call
1-800-552-3368.
h) Connection to party line service is subject
to state tariffs. Contact the state public utility
commission, public service commission or
corporation commission for information.

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.

Canada technical specifications.
Before installing this equipment, users should
ensure that it is permissible to be connected
to the facilities of the local telecommunica-

nection. 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 exten-
sion cord). The customer should be aware
that compliance with the above conditions
may not prevent degradation of service in
some situations.
CAUTION: Users should not attempt to make
such connections themselves, but should
contact the appropriate electrical inspection
authority, or electrician, as appropriate.

cation of the maximum number of terminals
allowed to be connected to a telephone

of the Ringer Equivalence Numbers of all
the devices does not exceed five.
Repairs to certified equipment should be
made by an authorized Canadian mainte-
nance 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.
