B. Ten Minute Function: After the correct value for hours is set, push the RESET
pad again. The blinking decimal will now move one digit to the right between digits
3 and 4. Pushing the UP or DOWN arrow pads will increase or decrease the ten
minute function allowing values between 0 and 5 to be set (digit 3).
C. One Minute Function: After the correct ten minutes value is set, push the RESET
pad again. The blinking decimal point will move one digit to the right beyond digit 4
and be located at the extreme bottom right of the display. With the display in this
mode, pushing the UP or DOWN arrow pad will increase or decrease the one
minute function allowing the value of digit 4 to be adjusted between 0 and 9.
D. Activation: Pause until the timer stops blinking. After all settings are made, push
the START/STOP button. The Timer Activated light will come on and after a brief
pause, the present oven temperature settings will be valid and heating will begin.
The oven will now heat up, control at the set point and stop after the timed period on
the SET/TIMER display has elapsed.
Note that when the system is in the timer mode, the heating circuit is de-energized
until the START/STOP button is pushed or the TIMER SWITCH is turned Off. If a
time change or correction is necessary and the timer has already been activated,
push the START/STOP button to "STOP" the timer, then repeat steps A through D
above.
6.7 To set the timer so that timed operation will not start until the oven is stable at set point, pre-
heat the oven in the normal mode until the desired temperature has stabilized. Turn on the
timer switch. Push and hold the RESET button until the timer display blinks. (This is to be
sure that the pre-set timed value is correct). Press the START/STOP button to activate the
timer.
