Determine Correct Voltage and Unit Setup
1. Verify voltage at outlet or junction box. Make
sure that the voltage is checked between L1 and L2
and from each leg to ground. Each reading should
be within 5% of each other.
2. Verify unit setup by beginning in the
off mode.
Hold the Cook Key and the Down Arrow Key at
the same time until you hear a brief beep. If you
hear two brief beeps, the oven is not in the off mode.
The oven will display it's setup information.

Changing the Voltage Setting:
Password 3838
With the oven in the off mode, push and hold
the Up and Down Arrow Key at the same time.
After 4 seconds, the display will show a zero
along with 3 dashes. Using the Up Arrow Key,
toggle up until the display shows a 3, then
push the Start Key. Using the Down Arrow
Key, toggle down until the display shows a 8
and push the Start Key. Using the Up Arrow
Key, toggle up until the display shows a 3 and
push the Start Key. Using the Down Arrow
Key, toggle down until the display shows an 8
and push the Start Key. The current set volt-
age will display.
If the setting needs to be changed, use the Up
or Down Arrow Key to select the proper volt-
age as measured at the outlet and then push
the Start Key. The voltage is now set for the
supplied voltage.
The control defaults to 240V on all models except
the 500-TH/III, 125V model. The default for this
unit is 120V. The oven control must be set to the
line voltage provided by your electric power sup-
plier in order to perform correctly. As an added
benefit, the unit will operate economically with an
average wattage draw much lower than those stat-
ed on the rating tag as shown below in Table C.
