FCC compliance
This equipment complies with Part 68 of the FCC Rules. On this equipment is a label that contains,
among other information, the FCC registration number and Ringer Equivalence Number (REN) for this
equipment. You must, upon request, provide this information to your telephone company.
If your telephone equipment causes harm to the telephone network, the Telephone Company may
discontinue your service temporarily. If possible, they will notify in advance. But, if advance 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.
Your telephone company may make changes in its facilities, equipment, operations, or procedures
that could affect proper operation of your equipment. If they do, you will be notified in advance to give
you an opportunity to maintain uninterrupted telephone service. The FCC prohibits this equipment to
be connected to party lines or coin-telephone service.
In the event that this equipment should fail to operate properly, disconnect the equipment from the
phone line to determine if it is causing the problem. If the problem is with the equipment, discontinue
use and contact your dealer or vendor.
DOC compliance information
NOTICE: The Canadian Department of Communications label identifies certified equipment. This
certification means that the equipment meets certain telecommunications network protective,

SAR715PV User’s Guide
3
operational and safety requirements. The Department does not guarantee the equipment will operate
to the user’s satisfaction.
Before installing this equipment, users 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. The customer should be aware that compliance with the above conditions
might 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.
CAUTION: Users should not attempt to make such connections themselves, but should contact the
appropriate electric inspection authority, or electrician, as appropriate.
NOTICE: 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 sum of the Load Numbers of all the devices does not exceed 100.
European CTR 21 compliance
The equipment has been approved in accordance with Council Decision 98/482/EC for pan-European
single terminal connection to the public switched telephone network (PSTN). However, due to
differences between the individual PSTNs provided in different countries, the approval does not, of
itself, give an unconditional assurance of successful operation on every PSTN network termination
point. In the event of problem, you should contact your equipment supplier in the first instance.
