WARNING
Electronic models of these appliances are equipped with a three-prong (grounding)
plug utilized in connecting the electronic components to the junction box in the lower
compartment. This grounding plug provides protection against shock hazard and should be
plugged directly into a properly grounded three-prong receptacle. DO NOT cut or remove the
grounding prong from the plug.
