Push BAKE pad.
Push SLEWpad untilan oven
temperature greaterthan 500°F
displays.
I Immediately pushand hold BAKEpad
until"00" displays,approximately 5
seconds.
To decrease oven teroperatara (for a
cooler oven), Push SLEWpad until
negative numbers appear, Oven can be
adjustedfrom -05 ° to -35° ower. To
avoid over adjustingoven move
temperature -5° each time.
To increase oventemperature (for a
warmer oven), Push SLEWped until
positive numbersappear. Oven can be
adjusted from 5" to 35° higher.To avoid
over adjustingoven move temperature
5° each time.
Push OVEN CANCEL button.
Temperature adjustment willbe
retained even through a powerfailure.
Control willautomaticallycancel any
cookingoperationand remove all relay
ddves 12 hoursafter the last pad touch.
Control input features willbe disabled
and display will indicate"OFF", when
BAKE and CLOCK are pushed
simultaneouslyand held for 5 seconds.
Control will returnto normal operat on
by repeatingthe procedure.
