(Revised 1/02)
The altitude of operation can be programmed into the Convection Combo. At
altitudes above 5,000 feet, the unit will not operate in Steamer or Combo Mode
unless the altitude is set. To set the altitude:
1. If the unit is on, turn it off by pressing the ON touch pad.
2. Press and hold the STEAM touch pad while turning the unit on by pressing the
ON touch pad. The timer display will show the letters AL and a number that
represents the altitude in thousands of feet. If the altitude has never been set
on your unit, the number displayed will be 0.
3. Enter the proper altitude value, between 0 and 15, using the numbered touch
pads. For example, if the unit will be used at an altitude of 7,000 feet, press
the 7 touch pad.
4. Press the START touch pad.
