the procedure of replacing and checking parts to be replaced.

circuits by checking general operations of the MEM-83, MA-83, DSP-78, and EQ-66 boards by All
Check.

tection mode" for tape transport system errors in the range of the 2xxx error codes.
For the 1xxx error codes, the cassette can be removed by the emergency eject SW.
* Cleaning means to clean using GW-90CL, as well as cleaning the tape running system using a cleaning
cloth and cleaning liquid during periodic inspections, etc.
