CAUTION
Repairs should only be done by a trained servicer.
Improper repair of your appliance may result in risk 
of severe physical injury or death.
Normal operating noises of the cooktop
Induction technology is based on the creation of 
electromagnetic fields. They may generate heat directly 
on the bottom of the cookware. Pots and pans may 
cause a variety of noises or vibrations depending on the 
way they've been manufactured. These noises are 
described as follows:
Low humming (like a transformer)
This noise is produced when cooking at a high heat 
level. It is based on the amount of energy transferred 
from the cooktop to the cookware. The noise ceases or 
quiets down when the heat level is reduced.
Quiet whistling
This noise is produced when the cooking vessel is 
empty. It ceases once water or food is placed in the 
vessel.
