A21A2 ADJUSTMENT (37397A)

ADJUSTMENTS

NOTE

Also save the calibration data to floppy disk for archival purposes as a backup in case of a hard disk failure. Label the disk with cali- bration type, date, and system model and se- rial numbers. Set the copy protect tab on the disk. Properly safeguard the disk so that it will be available for later use, as needed.

 

If calibration fails:

 

￿ Repeat the calibration. If it still fails, then proceed to Chapter 5,

 

Troubleshooting.
