Apply power to the oven.

will appear on the display.

If the Real-time Clock option is installed and 

[SetUp] 

/

[time] 

is programmed, the

time of day will appear on the display.

Preheat

If the 

[ready]

parameter under the 

[SetUp]

function in the Configuration Mode is set

to 

[``yes]

, the controller will detect temperatures and preheat to operating tempera-

ture (above relative set point minus the ready band).

Press the key for the menu you want to run. Each key selects a different menu. You
can select from up to six menus that control temperature and cooking time. Only
one menu may be run at a time.

Note: The controller will not respond if you select an invalid menu (the sum of Time 1 and Time 2 is 0).

The menu you have chosen becomes the current menu for controller operation. Until the
menu is completed or canceled, the indicator above the menu key will light up (flashing
or steady) to indicate the active menu.

•  If the oven is not at operating temperature, it will preheat. Meanwhile:

The word 

[Pre-`] [`Heat]

will appear on the display for a few moments. The menu

key indicator light will flash slowly. The temperature of Channel 1 will be displayed
until the operating temperature is reached.

(The Heat output indicator light — G, just below the display — will light up whenever
the controller is calling for heat.)
