12-hour,

24-hour or clock blackout

12-hour shut off

Your control is set to use a 12-hour clock. If you would prefer to have a 24-hour military time clock or black out the clock display, follow the steps below.

1Press the BAKE and BROIL HIGH/LOW pads (on double oven models, use the upper oven controls) at the same time for 3 seconds until the display shows “SF.”

2Press the CLOCK pad once. The display will show “12 hr.” If this is the choice you want, press the START pad.

Press the CLOCK pad again to change to the 24-hour military time clock. The display will show “24 hr.” If this is the choice you want, press the START pad.

Press the CLOCK pad again to black out the clock display. The display will show “OFF.”

If this is the choice you want, press the START pad.

NOTE: If the clock is in the black-out mode, you will not be able to use the Delay Start function.

With this feature, should you forget and leave the oven on, the control will automatically turn off the oven after 12 hours during baking functions or after 3 hours during a broil function. If you wish to turn off this feature, follow the steps below.

1Press the BAKE and BROIL HIGH/LOW pads (on double oven models, use the upper oven controls) at the same time for 3 seconds until the display shows “SF.”

2Press the DELAY START pad until “no shdn” (no shut-off) appears in the display.

3Press the START pad to activate the no shut-off and leave the control set in this special features mode.

NOTE: On double oven models, this activates this special feature in both ovens.
