To Set the Clock
The clock must be set to the correct time
of day for the automatic oven timing
functions to work properly. The time of
day cannot be changed during a timed
baking or self-cleaning cycle.
To Set the Timer
Press the KITCHEN TIMER ON/OFF
pad.
Press the number pads until the
amount of time you want shows
in the display. For example, to set
2 hours and 45 minutes, press 2, 4
and 5 in that order. If you make a
mistake press the KITCHEN TIMER
ON/OFF pad and begin again.
Press the START pad.
When the timer reaches :00 ,
the control will beep 3 times
followed by one beep every 6
seconds until the KITCHEN TIMER
ON/OFF pad is pressed.
To Reset the Timer
If the display is still showing the time
remaining, you may change it by pressing
the KITCHEN TIMER ON/OFF pad, then
press the number pads until the time
you want appears in the display.
To Cancel the Timer
Press the KITCHEN TIMER ON/OFF
pad twice.
Press the CLOCK pad.
Press the number pads.
Press the START pad.
The 6 second tone can be canceled by
following the steps in the Special features
of your oven control section under Tones
at the End of a Timed Cycle.
NOTE: On some models the time counts down
immediately when the START pad is pressed. The
timer is actually counting down in seconds that
are not shown on the display until the last minute.
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 KITCHEN TIMER ON/OFF pad
and then pressing the number pads to
enter the new time you want.
