The Pizzazz Plus
Adjust a cooking timer so the user can hear a "ding" when their food is done.
Impressions in this knob are noticeably for placing fingers.
Features a small arrow pointing to the current dialed setting. It is reasonably clear that this knob adjusts the timer for heating, although it is unclear whether or not heating will begin after adjusting this knob by itself.
Audible "ding" when the timer knob hits "0" whether or not the device is actually on.
Audible clicks when turning.
Automatically turns while cooking to indicate remaining cook time.
Adjusting a dial on a cooking appliance is typically for one of two things: relative heat or time. In this case, it's fairly clearly that turning the dial will set a time and that the system will stop cooking when the timer runs out.
Heat Settings Switch
Adjust the heat setting for the device. Food can be cooked from below, above, or both.
This "switch" features impressions on sides and text underneath. It isn't extremely evident whether or not to turn, twist, pull, push, slide, or press this "switch" until reading the text underneath.
Clicks into place when sliding, which helps the user understand if they're actually making adjustments.
Based on the text explanation alone, it's easy to assume that this switch affects the heating settings on the device. As a naive user, I'd likely keep this setting on "dual" at all times.
Rotating Food Platter
Defrost misc. frozen foods - pizza, corndogs, chicken, etc.
Fully cook misc. food - pizza, chicken nuggets, hot pockets, cinnamon rolls, etc.
Heat up food on top or bottom selectively
Serve food on platter
Heat surrounding area
The bumpy impressions and "CAUTION : HOT PAN" text signify the platter on which food should be placed. With appropriate context (understanding that this is for preparing food), this is a sufficient signifier.
Manually turning the platter offers resistance, which suggests that I shouldn't need to worry about manually adjusting it.
On first glance, I'm confused how this platter would cook my food from below. It looks like it just rotates food to be cooked from above. Regardless, there doesn't seem to be anything I need to do to make this platter do its job.
Power the pizza cooker.
Interestingly, there isn't a clear signifier for how to turn the device on. As a user, I am left to assume I just need to plug it in.
Plugging in the device visibly turns it on. The platter immediately starts turning.
It's a plug. I plug it in to turn the device on.
