The electronic key system contains incidental radio frequency generating circuitry and, if not installed and used

properly, may cause interference to radio and television reception. This equipment has been tested and found to

comply with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC Rules. These limits

are designed to provide reasonable protection against such interference when operated in a commercial environment.

Operation of this equipment in a residential area may cause interference to radio and television reception; in which

case the user is encouraged to take whatever measures may be required to correct the interference. If this equipment

does cause interference to radio or television reception, which can be 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: Reorient the

television or radio’s receiving antenna, and/or relocate the DSU, the individual telephone stations, and the radio or

TV with respect to each other. If necessary, the user should consult the manufacturer or an experienced

radio/television technician for additional suggestions. The user may find the following booklet prepared by the
