FCC REQUIREMENTS
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 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.

determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

If necessary, the user should consult the dealer or an experienced radio/television technician for additional
suggestions. The user may find the following booklet prepared by the FCC helpful: "How to Identify and Resolve
