FAULT MESSAGE
If the knobs have been kept rotated in the "A" or "P" positions
for more than 30 seconds a fault message will appear on the
display.
Cookware "noise"
When using adjacent elements that are set at certain power
level settings, magnetic fields may interact and produce a low
whistle or intermitted "hum". Pans that completely cover the
element ring will produce less noise. A low "humming" noise
is normal particularly on high settings. These noise can be
reduced or eliminated by lowering or raising the power level
settings of one or both of the elements.
