The installer must ensure that this control and its wiring are isolated and/or shielded from strong sources of electromagnetic

noise. Conversely, this Class B digital apparatus complies with Part 15 of the FCC Rules and meets all requirements of the

Canadian Interference-Causing Equipment Regulations. However, if this control does cause harmful interference to radio

or television reception, which is determined by turning the control off and on, the user is encouraged to try to correct the

interference by re-orientating or relocating the receiving antenna, relocating the receiver with respect to this control, and/or

connecting the control to a different circuit from that to which the receiver is connected.
