top of the cavity. To turn on the top heater, touch
the “Top Heater: Off” icon. To turn it off, touch
the icon again. The icon will display on or off,
depending on the status of the heater.
While the heater is on, the backlight behind the
“H1” status indicator at the bottom of the screen
should turn off. This means the top heater is on.
If the top heater is not heating up while the icon
indicates that it should be, see pages 48 and 52 for
troubleshooting.

bottom of the cavity. To turn on the bottom

heater.
While the heater is on, the backlight behind the
“H2” status indicator at the bottom of the screen

the icon indicates that it should be, see pages 48
