The manual that came with our electric stove does not show the same ICONs displayed in the manual.  Our electric stove has a "LOCK Picture" while the manual does not show such.  We accidently pushed this button while installing the stove and when we went to view how to cancel the icon we had nothing to tell us anything about this option.  We had to call service for explanation and they knew nothing about the "Lock" option in the display?   Just caused us concern until we were able to figure it out on our own.  Need manual specific to product.
