- New Test Mode
S-CD plays the same way as before.
If an error such as off focus, spindle unlocking, unreadable sub-code, or sound skipping occurs after setup, its
cause and time occurred (in absolute time) are displayed.
During setup, operational status of the control software (internal RAM: CPOINT) is displayed.
These displays and functions are prepared for enhancing aging in the servicing and efficiency of trouble analysis.
(1) Shifting to the New Test Mode
1 Turn on the current test mode by starting the reset from the key (it varies between the products).
2 Select S-CD for the source through the specified procedure including use of the [SOURCE] key, and inserting the
disc. Then, press the [Jump Mode Selector] key while maintaining the regulator turned off.
3 After the above operations, the new test mode remains on irrespective of whether the S-CD is turned on or off.
You can reset the new test mode by turning on the reset start.
* With some products, the new test mode can be reset through the same operations as that employed for shifting to
the STBY mode (while maintaining the Acc turned off).
