I have somehow locked my microwave and don’t know how to unlock it. When I press any button on the panel it says it’s locked.
How do I unlock this microwave. 
The following may help. I got it from an operators manual I founfd on the net.
The oven operation can be locked to prevent the microwave from accidentally being turned on.
All oven functions can be locked.
To Set:
Touch and hold the CANCEL/OFF Pad for
three seconds. The Display shows “LOCKED”
and the oven beeps.
To Cancel:
Touch and hold the CANCEL/OFF Pad for
three seconds. “LOCKED” disappears from the
Display and the oven beeps.
