From the Operation Manual, page 7-8:

1. Turn ON all 4 DIP switches on the drive.
2. Turn on the computer and the drive, and insert the utility disk.
3. Go into BASIC.
4. Enter this program:
      10 OPEN"COM:88N1DNN"FOR OUTPUT AS#1
      20 PRINT#1,"S10985157C00AD7EF08B3AS901FE"
      30 LOAD"COM:88N1ENN",R
      SAVE"IPL.BA"
5. Hit F8 to exit BASIC.
6. Run IPL.BA from the main menu.

Then you have to turn the drive's DIP switches OFF for normal operation.
The drive's low-battery indicator blinks fast if you have the switches
set wrong.
