Note

Note: After all steps are completed, check the ACT mode of TSW cards, which are in the same switching block with the replaced PLO. Because the PLO-located MUSIC ROM supplies hold tones only to the TSW cards belonging to the same switching block, verify all the TSW cards are also in the ACT-mode status. Refer to Section 12, System Control Procedures, in Chapter 6.
