You can download the Use Manual at Samsung.com. Yes, the section on the proof feature is below:

Proof
The proofing feature maintains a warm environment useful for rising yeast-leavened products.
1. To enter the Proof mode, press the Proof pad.
2. To start the proofing function, press the START/SET pad. The proofing feature automatically
provides the optimum temperature for the proof process, and therefore does not have a
temperature adjustment.
3. Press the CLEAR/OFF pad at any time to turn off the proofing feature.
• If you press the Proof pad when the oven temperature is above 100˚F, Hot will appear in the
display. Because these functions produce the best results when started while the oven is cool, we
recommend that you wait until the oven has cooled down and Hot disappears from the display.
• To avoid lowering the oven temperature and lengthening proofing time, do not open the oven door
unnecessarily.
• Check bread products early to avoid over-proofing.
• Do not use the proofing mode for warming food or keeping food hot. The proofing oven temperature
is not hot enough to hold foods at safe temperatures. Use the warm feature. (see next page).
• For best results, cover the dough with a cloth or with plastic wrap. The plastic may need to be
anchored underneath the container so the oven fan will not blow it off.
