Visonic Powermaster 33 factory reset

BJK01

Hello, I just bought a Visonic Powermaster 33 with KP 250 keypad on Ebay.

After enrolling the KP250, it does not accept the default codes 8888 and 9999 to enter the system or installer mode. Code 1111 is working as user code, but does not work to access the installer mode.
I found the following reset method on the internet:
Remove the mains power to the control panel.Open the control panel and disconnect the battery.Identify the 3 pins marked DEF.Fit a jumper across the D and E pins.Apply battery power to the panel for approximately 10 seconds.Remove battery power from the panel.Remove the jumper from the D and E pins.This does not work.
Who can help me?

Thanks,
BJK
