8753C Source Pretune

Hi --

As part of the troubleshooting of the test set problem I reported in another thread, I ended up doing the Source Pretune Correction Constants adjustment (tests 45 and then 48.

Test 45 completes with no issues.  Test 48 completes showing "DONE" but the asterisk is displayed on the left side of the screen and I need to press PRESET in order to get back to sweeping -- but the unit seems to perform normally after that.  I can squint at the instructions and guess that maybe PRESET is required, but it's not clear.

Is this normal or does it indicate a problem?  (This is firmware version 4.01, BTW).

Also, a really dumb question but the adjustment instructions end with "Refer to the EEPROM Backup Disk Procedure to store the new correction constants."  Am I correct that this procedure is only to create an updated floppy, and that the corrections are actually written to EEPROM as part of the test and doesn't require this step?
