8.2 Adjustment Procedure
– Connect the basic engine to the USB to ATAPI adapter
– Power on the adapter
– Connect the USB connector of the adapter to the PC.
Note that the USB bus supports "Hot Plugging". That
means the computer can already be switched on.
Alternatively you can connect the basic engine directly to
the IDE bus of a computer. In this case the adapter is not
necessary but the PC has to be switched off and must be
started up in order to detect the new drive on the IDE bus.
– Call up the applicator software, see figure 8-2
– Set the timeout to 50 seconds, see figure 8-3
– Run the "Adjust Laser Control" command, see figure 8-4.
– The "Status" indicator in the left section of the window has
to become green after successful adjustment.

following discs:
