Menu Cook Mode

The oven is preprogrammed with recipe settings at the time of manufacture and is ready to operate out of the box. New menu settings can be loaded via USB or smart card (page 21-22) or programmed manually (page 23). If settings are not present, the oven will cook only in manual mode (page 13).

This oven uses impingement and microwave to cook food faster than traditional cooking methods. Air enters the cavity from the top and bottom using a single fan. Because of this design and to ensure uniformity of cooking, the oven must be operated only while the bottom jetplate is in place. While the bottom jetplate is removable for cleaning, it is not removable for cooking. Without the bottom jetplate in place, the oven will not deliver the proper cooking performance to either the top or bottom of the food item. Additionally, oven damage may result.

The sequence of the steps below may vary, and some may not apply.

Step 1: Touch “Menu” or the Oven Set Temperature Icon to Turn the Oven On

Step 2: Select Cook Temperature

NOTE: If the temperatures are the same, or if Manual Mode is disabled, this screen will be bypassed.

Step 3: Warming Up

NOTE: When the oven is done warming up, it will “soak” for an additional eight minutes. “Soaking” ensures the cavity surfaces absorb enough heat so that cooking will not be affected.

Step 4: Place Food in the Oven

WARNING: Inside of oven and oven door are hot!

Step 5: Select a Group

NOTE: Touch “More Groups” to view additional groups.

Step 6: Select an Item

NOTE: Touch “More Items” to view additional items.

Step 7: Cooking

NOTE: To immediately terminate a cook cycle, touch “STOP.”

NOTE: If the oven door is opened during a cook cycle, the cycle will pause until the door is closed. Touch “YES” to resume.

Step 8: Check/Remove Food from Oven

WARNING: Dish/inside of oven and door are hot!

Step 9: Cook More / Brown More / Cook & Brown More

NOTE: This option must be enabled in order to cook an item beyond its original cook time (see page 15 for details).

To cook an item longer than its original cook time, touch one of the icons on the screen:

-Touch “Cook More” if the inside of the food item requires cooking.

-Touch “Brown More” if the outside of the food item requires browning or crisping.

-Touch “Cook & Brown More” if both the inside and outside of the food item require cooking.

Selecting one of these options will cook the item for 20% of the last cook time selected. The minimum cook time is the fewer of 15 seconds or the entire original cook cycle. The maximum cook time is one minute. The oven will cook at the settings listed below:

-Cook More: 10% air, 100% microwave

-Brown More: 100% air, 0% microwave

-Cook & Brown More: 100% air, 100% microwave

Step 10: Cooling Down
