I did not get a manual with the item.  I have requested one but have not receive one as of today.   I cannot find out how to change any of the setting.   Power or anything except setting the run time.   I normally us my microwave for about everything I cook.  I cannot understand why there was not a manual and especially I cannot understand that your company has not acknowledged my request.  It is very upsetting that I cannot use it for things that I always have.   I try to change setting ie Power Level -  It changes but as soon as I push start, it reverts back to what it was set at.
