MANUAL BACK-UP
Should the computer control system develop a
fault causing it not to function the Manual Back-
up Switch, when energized, will bypass the
computer and change the oven control to a
mechanical thermostat. This will allow the oven
to continue operating until service can be
performed on the computer.
The Manual Back-up can also be used until the
computer is programmed.
The switch for the Manual Back-up is located
behind the louvered door, below the control
panel.
When the Back-up switch in the On (up)
position the oven temperature is controlled by a
mechanical thermostat located next to the switch.
Rotate the thermostat knob clockwise until the
desired temperature appears at the top of the
knob.
When in the Manual Back-up mode, the
computer will turn completely off and will not
time any products.
If service is required on the Lang computer, refer
to the Lang Authorized Service Agency
Directory for the nearest repair agency.
