USING THE PRESS-AND-TURN CONTROL KNOBS
The control knobs are flush-mounted in the control panel.
Use them as follows:
a. Press lightly on the knob (figure 15-A);
b. The knob will extend outwards as illustrated in figure 15-B.
c. Turn the knob to the required position (figure 15-C).
d. When you have finished cooking, turn the knob back to the "0" (off) position and press
it (figure 15-D) so that it stays flush with the control panel again (figure 15-F).
IMPORTANT:
Never press down the knob when it is not in the "0" (off) position (figure 15-E).
