Question: Can you cook in it without using the timer?    With the "Stay On" setting do you have to go thru the timer to turn it ON or Off ?
Document: It has a timer that has a setting for light toast and dark toast. The oven won't turn on without the timer being set, but there's a feature that allows continuous heating without using the timer. The temp. range is 150-450 degrees F.It is pretty much pointless to use this to make toast. It takes forever and the toast feature is useless along with the other functions (aside from the convection feature)!
This oven looks nice on your counter top, but it's poorly designed and awkward to use. There are a number of silly, non-intuitive cooking modes. Some of these appear to override the front panel temperature setting. Why?! The inaccurate timer means that there's no reproducible way to make toast. If I turn the timer just a tad too far, my pita goes up in flames. Oster should stop letting its marketing department design products without actually testing them in the real world.
The timer or the toast setting is a bit deceiving and it is very easy to burn toast. Be sure not to leave the kitchen when using the toaster setting.
If you are trying to do a short toasting, you have to twist it past 10 min and then bring it back towards zero. On the other side of zero is a strange feature where the oven will never turn off. After using the oven for a little over a year, we noticed that the dial must have slipped, because the oven no longer turns off when toasting - even though the little indicater is set for 5 min, it acts as though you have set it to stay on indefinitely.
My mom loved this product. She found numerous uses and it fit perfect in her kitchen. She did have to work a bit on the knob for the timer as it was a little difficult to turn. But is now loosening up with use.
I had a B&D Toaster oven for years and I used it some and, well, more often lately. It was better than using the big oven. Then I decided I could cook bigger stuff if I had a bigger oven. So I read reviews, and looked and looked. I didn't want something that dominated a whole section of counter. or that I could use to cook a huge turkey.
I purchased this toaster oven about 2 months ago to replace one that caught on fire while the wife left her toast unattented (she used the tempature setting rather than the toast setting). I really like this toaster oven. The convection setting is great for frozen waffles, chicken nuggets, pizza, frozen bread, toast, etc. The waffles are cooked evenly and to perfection in 3 minutes without pre-heating the oven!! The oven looks great, however it is a bit larger than most others.
My best guess is that there is an internal safety feature to prevent the oven from overheating and that when I attempted to cook to batches of sweet potatoes back to back, I must have triggered this feature to turn off the heating element of the oven (odd that the convection fan continued to run though). I hope that's the case, because I would hate to lose this oven!As long as I'm editing, I notice that a number of toaster oven review address the heat on the exterior of the oven.
Plan on watching your toast for the last minute to grab it before it gets too dark.If you want a small oven to cook for 1 or 2 people, this will do the job nicely. But if you plan to use it mainly for toasting, a pop-up toaster is probably a better choice.
), cook small entrees, pizzas. etc. We used it every day and it was always great - until yesterday. Too bad it died the day before Thanksgiving - I had big plans for it today, but I guess I'll have to cram everything in my regular oven.
Answer: Yes you can cook with it set to " Stay On" with out using the timer. To turn off just turn knob back to  " 0" on timer setting.
