Yes, a fairly poor one. It does not show what temperature
range its convection feature will accept. It automatically
switches to power level input after you have pressed enough
keys to be understood as a time. Microwave time input is
minutes+seconds while convection input is hours+minutes. It
does count the cooking time down nicely though.

Yes, again a quite poor one. For example,
<http://www.audiforums.com/forum/showthread.php?t=81683>.
People are generally baffled by the light. It goes on, it
goes off, it flashes, and in general it utterly fails to
communicate any information to the user beyond "something
might be wrong".
