Step 4. Follow the directions displayed on the 373XXA CRT screen, until calibration is completed.

Post Calibration After the calibration process is completed, perform the following ac- Actions tions, as appropriate:

If calibration passes:

Save the calibration data to (hard) disk, as follows:

Step 1. Press the Option Menu key (Enhancement key group) to dis- play the OPTIONS menu.

Step 2. Select DIAGNOSTICS from menu.Then select in se- quence: H/W CALIBRATIONS DISK OPERATIONS SAVE TO HARD DISK HW_CAL.FRE.

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 (FRE), date, and system model and serial numbers. Set the copy protect tab on the disk. Properly safeguard the disk so that it will be available for later use, as needed.

Perform the Source FM/Lock Linearity test in Chapter 3, Operational

Tests. If the test fails, proceed to Chapter 5, Troubleshooting.
