A:AnswerHi KB, thank you for your inquiry. The following will happen in regards to the beep.
Beep Sound:
When a pad is pressed correctly, a beep will be heard.
If a pad is pressed and no beep is heard, the unit did not or cannot accept the instruction.
When operating, the oven will beep twice between programmed stages. At the end of any
complete program, the oven will beep 5 times.
A:AnswerI normally don’t cook in it unless really short on time so far I just cooked rice in it usingI a collapsible vented microwave cover I always keep it inside ready to use, it cooked perfectly fine not temperature adjusting etc, so I think it doesn’t affect it but you can always call the company and check.
