Cautions: 1)While the test mode is started, the abnormality in mechanism is ignored and operation is perf

30、ormed: If any abnormality is detected in operation, immediately unplug the power cord. 2)During test mode, normal playback or recording is not possible. Key Operation in Test Mode and MD Electrical Adjustment: After the test mode has started, the operation panel will not turn. Perform key operation

31、using either of the following procedures: Key operation on remote control Turn the pulley on PWB, CD so that key operation on MD EDIT STAGE on the operation panel is possible. (See the figure below) -14- 2. Checking MD Test Mode and Audio Output 1) After the test mode has started, the display will b
