Servo Monitor can be used for the DP-L mechanism. -6- Ill. Operating Specifications The automatic adjustment operations of the CM0-7837R/COM-7834R are performed by output of the commands of the various adjustment items from the main microprocessor. Adjustments are performed in response to these commands by the digital servo LSI. This servo monitor jig receives the signal returned to the main microprocessor from the digital servo LSI and causes the LED to light or go off. The adjustment condition (of either completed or not yet completed) of the various adjustment items can be checked using the lighting condition of this LEO. The following test discs are required for the good/fault judgment: 1. A-BEX TCD-721 (6th track 1.2mm): Scratch test disc 2. A-BEX TC0-782: Signal test disc Measures to be Taken Corresponding to the LED Indication COM-7837R/ COM-7834R 1. When a LED other than FAGC or TAGG lights, perform the fault causation analysis using the fault diagnosis chart according to the LED indication. 2. When only the FAGG or TAGG LED turn on a lights (indicating that the focus/ tracking fine gain adjustment is not completed) , perform the focus/ tracking servo gain adjustment. If the value is within the specification, the adjustment is normal. i) LED indications lit .
