New Test Mode
When S-CD is specified as the source, basically the system plays as normal operation. After setup, the system dis-
plays the cause and time (absolute time) of an error if focus search is improper, spindle lock is removed, subcode
cannot be read, or sound is skipped. During setup, the system displays the operation status of CD control software
(internal RAM : CPOINT). The purpose of these displays and functions are to detect aging of servicing, as well as to
improve efficiency of defect analysis.
(1) How to enter NEW TEST Mode
1. Reset the system by pressing keys (depending on the product) to enter the conventional Test mode.
2. Select S-CD as the source by pressing the source or CD key, then inserting a disc. Confirm that the regulator is
OFF. Press the Switch Jump Mode key.
3. After that, the system will stay in the new Test mode, regardless of whether S-CD is OFF or ON.
To exit from the new Test mode, reset the system.
See the test mode flow chart Page 53.
