In addition to restriction notification, the FCC requires that
Cermetek make all repairs to all products in the HS Modem
family. If repairs are necessary after installation of the HS
Modem and the end product has been delivered to the end
user, the end product must be returned to the end product
supplier where the HS Modem can be removed and then
forwarded to Cermetek repair. The following notice is
recommended and should be included in the end product’s
user manual.
FOR YOUR USER’S MANUAL
The part 68 rules require the following (or equivalent) be
provided to the end user of the equipment containing a

designed to be used on standard device telephone lines. It
connects to the telephone line by means of a standard jack
called the USOC RJ-11C (or USOC RJ45S). Connection to
telephone-company-provided coin service (central office
implemented systems) is prohibited. Connection to party
lines service is subject to state tariffs.
Changes in Attestation Procedure for Plugs and Jacks:
(Name of applicant) attests that the network interface plugs
or jacks used on this equipment comply with and will
continue to comply with the mechanical requirements
specified in Part 68, Sub-part F, specifically the

incoming
inspection.
Telephone Company Procedure:
The goal of the
telephone company is to provide you with the best service
it can. In order to do this, it may occasionally be necessary
for them to make changes in their equipment, operations or
procedures. If these changes might effect your service or
the operation of your equipment, the telephone company
will give you notice, in writing, to allow you to make any
changes necessary to maintain uninterrupted service.
In certain circumstances, it may be necessary for the
telephone company to request information from you
concerning the equipment which you have connected to
your telephone line. Upon request of the telephone
company, provide the FCC registration number and the
ringer equivalence number (REN); both of these items are
listed on the equipment label. The sum of all of the REN’s
on your telephone lines should be less than five in order to
assure proper service from the telephone company. In
some cases, a sum of five may not be useable on a given
line. Consult your telephone provider.
If Problems Arise:
If any of your telephone equipment is
not operating properly, you should immediately remove it
from your telephone line, as it may cause harm to the
telephone network. If the telephone company notes a
problem, they may temporarily discontinue service. When
practical, they will notify you in advance of this
disconnection. If advance notice is not feasible, you will be
notified as soon as possible.
When you are notified, you will be given the opportunity to
correct the problem and informed of your right to a file a
complaint with the FCC. Contact your local telephone
service provider if you have any questions about your phone
line.
In the event repairs are ever needed on the (insert your
product name), they should be performed by (insert your
company name) or an authorized representative of (insert
your company name). For information contact: (insert your
company address).
