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 DXP, 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
