INSTALLATION
When you are ready to install this system, call your telephone company and give them the following
information:
1. The telephone number of the line to which you will connect the system.
2. The FCC registration number for the system, which is DS83E7 - 17196 - ALE.
3. The ringer equivalence number (REN) which is 0.1B.
This system connects to the telephone line by means of a standard jack called the USOC RJ11C. If this type
of jack is not available where you want to install the system, you will need to order it from the telephone
company.
TYPE OF SERVICE
Your LiftMaster Model SW 2000-X3 operator is designed to be used on standard-device telephone lines.
They should not be used on coin service or party lines. If you have any questions about your telephone line,
such as how may pieces of equipment you can connect to it, the telephone company will provide this
information upon request.
TELEPHONE COMPANY PROCEDURES
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 affect your service or 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.
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 telephone network. If the telephone company notes a problem, they
may temporarily discontinue service. When practical, they will notify you in advance of this documentation. 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 file a complaint with the FCC.
In the event that any repairs are ever needed on your system, they should be performed only by an
authorized representative of LiftMaster, Inc.
DISCONNECTION
If you should ever decide to permanently disconnect your operator from its present line, please call the
telephone company and let them know of this change.
