Mi DISPLAY FUNCTION OF AUTOMATICALLY-ADJUSTED RESULTS
(SELF-CHECK FUNCTION)
The unit contains a function which displays the result of the automatically adjustment of the servo circuits
(tracking, forcus servo, etc.) as an error code on the FL display.
The error code display serves as a repair guide showing the automatically adjustment circuit is at fault.
The
procedures for displaying the error codes are given below.
e Procedures to display the error code
(1) While simultaneously pressing and holding the three keys, [li
STOP], [B— PAUSE], and [> PLAY], press the
key.
When the unit is turned on and the FL display is lit up, immediately release the three keys.
(2) Press the
key to open the disc tray, load the test disc (SZZP1054C) on the tray, close the
tray by pressing the
key again.
An error code will appear on the FL display (e.g. "E-00").
(3) The error code provides a rough indication of which servo circuit is malfunctioning.
e Error code based troubleshooting
> The unit is satisfactory if the error code is E-00 of E-02.
>< Before testing, check that the test disc is free of scratches and dirt and optical pickup is clean.
