Notes: 1)Mechanical abnormalities are ignored while the test mode is starting up. If any abnormality occurs, disconnect the plug immediately. 2)During test mode operation, p

37、layback and recording are normally not possible. 2. Checking the MD Test Mode Indication About five seconds later after the test mode starts, characters as shown in the below figure appear on the screen and the test mode becomes usable. 3. Canceling the MD Test Mode 1)Press the MD EJECT button to ej

38、ect the disk. 2)Disconnect the AC plug. *If the MD test mode is canceled by procedures other than the above, the unit sometimes run incorrectly. If this happens, disconnect the AC plug. 4. Switching to the Servo Standby Mode After starting up the test mode, press the STOP key to switch to the servo

39、standby mode. (Indication: ALL SV OFF) Change from this mode to each mode. When the STOP key is pressed in each mode, the display returns to “ALL SV OFF”. 5. Notes during Test Mode Operation If the test mode starts up, the touch sensor of the operation panel does not run. Operate in the following wa

40、ys. 1)Use the remote controller. 2)Rotate the pulley that is visible from the hole of the CD board by hand to rotate the operation panel. 6. Checking the Sled Feed Operation 1)Press the F.SKIP button in the “ALL SV OFF” state to move the lens and pickup to the outer circumference. Then “T.SLED FWD”

41、is displayed. 2)Press the B.SKIP button in the “ALL SV OFF” state to move the lens and pickup to the inner circumference. Then “T.SLED RVS” is displayed. Set the INSIDE LIMIT switch to ON to light the frame of graphic equalizer “JAZZ” of the display. 7. Checking the Laser Power 1)Every time the MD E

42、DIT button is pressed in the “ALL SV OFF” state, the display is switched as shown below. 2)After checking, press the STOP button to return the display to “ALL SV OFF”. 8. Checking the Loading Mechanism and OWH to check the operations of the loading mechanism and OWH, follow the procedure given below
