1. TO SWITCH ON / OFF
With the green light indicating that the electricity supply is connected (lightning), press the
ON/OFF button for a moment; the display will light up indicating, after about ten seconds, the
temperature reading inside the oven (red light above the thermometer will be on); the rotation
speed of the plate will be that of “oven standby”.
To switch off the console, press the ON/OFF button for a few seconds until it switches off.
Use the “EMERGENCY” button only in case of necessity.
2. BASE LEVEL COOKING
Move the joystick down for a moment (towards the lit dot above the “clock” symbol); the
rotation speed of the plate will change to the optimal speed for cooking; the display will show
the cooking time remaining, with time being counted down; ten seconds before cooking is
finished, there will be a short warning sound indicating “cooking almost finished” and at the end
there will be three short sounds.
3. COOKING WITH THE PLATE AT THE 1ST LEVEL
Move the joystick lever to the left for a moment; the plate will rise to the first level and cooking
will take place as for the “BASE LEVEL COOKING”. When cooking is finished, the plate will
descend to the base level. For safety, the command will be refused if the temperature
registered inside the oven is less than 150°C.
4. COOKING WITH THE PLATE AT THE 2ND LEVEL
Move the joystick lever to the right for a moment. Everything will function as for cooking at the
1st level, but obviously at a higher level. When cooking is finished, the plate will descend to the
base level. For safety, the command will be refused if the temperature registered inside the
oven is less than 150°C.
5. TO PRE-HEAT THE PLATE
Move the joystick lever upwards for a moment; the plate will rise to the maximum height, and
rotation speed will be that during cooking, and for a pre-set time, at the end of which the plate
will descent to the base level.
For safety, the command will be refused in the temperature registered inside the oven is less
than 150°C.
6. TO IMMEDIATELY HALT COOKING IN PROGRESS
For all cooking methods or pre-heating the plate, keep the joystick pressed downwards for a
couple of seconds. Cooking or pre-heating will stop immediately, and the plate will descend to
the base (function RESET).
7. TO STOP ROTATION OF THE PLATE
Press the ON/OFF button for a moment; the plate will slow down and then stop. Pressing the
button again in the same way will cause the rotation to return to the normal speed again.

8. TO VARY THE COOKING TIME
During the “standby” phase, press the “SET” button for a moment; the green light near the clock
symbol will flash; duration of the cooking time will be shown on the display. The time can be
increased or decreased as desired by pushing the joystick (to the right or left); keep the SET
button pressed to confirm or wait for the automatic “exit”.
9. TO VARY THE ROTATION SPEED OF THE PLATE DURING COOKING
Briefly press the SET button twice (the green led with the entering hare will flash). With the joystick
towards + or –increase or decrease the revolutions per minute as desired. Exit from the
regulation mode by keeping the “SET” button pressed for a few seconds or wait for the
automatic exit.
10. TO VARY THE ROTATION SPEED OF THE PLATE DURING “EXTRACTION”
At the end of the cooking time, the extraction time begins. The rotation speed can be set by
pressing the “SET” button three times (the green led with the exiting hare will flash); use the
joystick to increase or decrease the revolutions/minute as desired.
Exit from the regulation mode by keeping the “SET” button pressed for a few seconds or wait
for the automatic exit.
11. TO CHANGE ROTATION DIRECTION OF THE PLATE
Switch off the control panel with the ON/OFF button, keeping the joystick lever pushed
towards the desired rotation direction (left or right). Switch on the control panel again with the
same button, releasing the lever after hearing a short sound.
12. TO CHANGE THE SOUND OF THE ACOUSTIC SIGNALS
Keeping the “SET” button pressed even after obtaining the desired sound, move the joystick
lever (towards the left or right) to modify the sound as desired; when the joystick is released,
the sound will be permanently memorised.
13. TO POSITION THE PLATE FOR MAINTENANCE
Switch off the control panel with the ON/OFF button, wait a few seconds, then switch on
again, keeping the joystick lever pushed upwards until all the horizontal lines appear on the
display.
At this point, rotation is blocked and with the joystick (pushed upwards), the plate can be
raised or lowered as desired, even if the temperature is below 150°C.
14. CONTROL VERSION OF PROGRAMME
For the first 5 seconds after switching on (with the ON/OFF button), the display shows which
release of the function programme version is being used: “r.07” = release 7.
