Push EN and the following screen will appear (Pic. 5). From now on, this screen will be called MAIN MENU. -
Page 7: Programs
3.5 - Programs The furnace PF Pro can store up to 100 programs (or cycles): 79 are programs for complete firing cycles for tradictional ceramics and 20 are suited for CAD/CAM lithium disilicate. The program 0 is a test cycle which should not be used for firing. -
Page 8: B Change A Program
Rotate EN to modify it. Push EN twice to switch again to F2. Rotate EN to move to F3 and proceed like this until the last function F15. You can go back or skip the functions which don’t need to be modified. After having set the complete program, push ESC and the following screen will appear: Pic. - Page 9 From this position you can view the program and, if you want, you can also change it. Once the program has been chosen, push ENTER: in this way you will access the display shown in Pic. 8. As described in 3.5A, you can see the program and even change it. At the end, by pushing ESC, you move to the save function display shown in Pic.

4 - CRYSTALLIZATION OF CAD/CAM LITHIUM DISILICATE PF Pro can treat CAD/CAM milled lithium disilicate. The corresponding cycles are included between position 80 and 99. These cycles are characterized by a high number of editable parameters (instead of only 15 parameters, here 23 parameters are present). -

B – Manual Calibration: it is useful when the dental technician has to perform small changes depending on the verification of the ceramic after firing it. It is clear that each furnace must be customised according to the user and therefore it is possible to introduce small manual changes as for the furnace calibration: To modify manually the calibration please follow the hereafter instructions: enter the Calibration menu select the function OFFSET by rotating EN and then press ENTER... -

Pic. 17 CUR Li UP : this parameter is proportional to the max torque the engine can use for the lifting of the plate. Its default value is 850 and it is recommended not to change it. CUR Li DO : this parameter is proportional to the max torque the engine can use for the lowering of the plate. -
Page 14: Recommendations For Use
This menu is used for the following tests on the furnace: Pump performance and vacuum-tightness. By choosing Air Out=ON and Vacuum=ON (after of course having closed the muffle) you turn On the pump and you check what level of vacuum is able to produce. -
Page 15: Error Messages
8.3 - Error messages When an error intervenes, the furnace emits an intermittent sound signal and on the main display the heading “Problem” followed by a number will appear. The numbers correspond to the following inconveniences: Problem Description Reading / writing problem of the EEPROM. The electronic card doesn’t work! Contact the manufacturer. -
