Actually, the timer doesn't seem to stop beeping and there doesn't seem to be a way to turn off the beeping other than hitting the stop/start button. Slightly annoying but not a big deal. The unit does continue to run while the timer is going off. It does not beep when it comes up to temperature, and while that would be a nice feature, it's not necessary. Without having the original unit, it's difficult to know the differences. It does look like the temperature calibration is easier to access from the boot screen at the beginning. The manual does not appear to be any different than the one I read online originally, but feel free to download it. Ooops, I fibbed about this. If you hit the area where the timer is, it does indeed stop the timer without stopping the unit. Also, here's the burger I made with the unit last night.
