6. To exit from this mode, perform as follows:
1) Move the pickup to the most inside track.
2) Press three buttons in the same manner as step 2.
Note: • Always move the pickup to most inside track when exiting from
this mode. Otherwise, a disc will not be unloaded.
• Do not run the sled motor excessively, otherwise the gear can be chipped.

of fluorescent indicator tube changes to “MW 9 k STEP” or “MW 10 k STEP”, and thus the channel step is changed over.
[GC Test Mode]
• This mode is used to check the software version, FL tube, LED, keyboard and VACS.
Procedure:
1. Press three buttons x , ENTER , and DISC 2 simultaneously.
2. LEDs and fluorescent indicator tube are all turned on.
3. When you want to enter the software version display mode,
press DISC 1 . The model number and destination are displayed.

(3) The mechanism accesses DISC 3 and a message “CD3 NO
DISC” appears. (4) The disc tray turns to select a disc1. (5) A disc is chucked. (6) TOC of disc is read. (7) The pickup accesses to the track 1, and playing 2 seconds. (8) The pickup accesses to the last track, and playing 2 seconds. (9) Every time when an aging operation of step 1 to step 8 is
complete, the display “AGING[*][*][*][*]” value increases
as the number of aging operations is counted up. (10) Returns to step 1.
