Using the timer

1Press the TIMER ON/OFF pad.

2Press the number pads to set the time. For example, to enter 2 hours and 45 minutes, touch 2, 4 and 5 in that order.

If you make a mistake, press the TIMER ON/OFF pad and begin again.

3Press the START pad.

After pressing the START pad, “SET” disappears; this tells you the time is counting down, although the display does not change until one minute has passed. Seconds will not be shown in the display until the last minute is counting down.

4When time is up, the oven control signals until you press the TIMER ON/OFF pad. Display then shows the time of day.

NOTE: The minute timer is independent of all the other functions and it does not control the oven. The CLEAR/OFF pad does not affect the timer.

To reset the timer:

If the display is still showing the time remaining, you may change it by pressing the TIMER ON/OFF pad, then press the number pads until the time you want appears in the display.

If the remaining time is not in the display (clock, delay start or cooking time are in the display), recall the remaining time by pressing the TIMER ON/OFF pad and then pressing the number pads to enter the new time you want.

To cancel the timer:

Press the TIMER ON/OFF pad twice.

Control lockout

Your control will allow you to lock out the touch pads so they cannot be activated when pressed.

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

To lock/unlock the controls:

1Press the 9 and 0 pads at the same time for 3 seconds, until the display shows “LOC ON.”

2To unlock the control, press the 9 and 0 pads (on double oven models, use the upper oven controls) at the same time for 3 seconds, until the display shows “LOC OFF.”

When this feature is on and the touch pads are pressed, the control will beep and the display will show “LOC ON.”

NOTES:

•The control lockout mode affects all touch pads. No touch pads will work when this feature is activated.

•The adjustment will be retained in memory after a power failure.
