Measurements And Adjustments - Panasonic SL-CT570 Manual

<Example>
Follow the below steps when "E-1" is displayed.
(Cause: Focus balance (FBC) is set beyond the limit.)
Check if
(1) the waveform or voltage of the focus servo circuit is correct. (check the waveform or voltage.)
(2) the optical pickup returns to the normal state by exchanging the traverse deck.
Follow the below steps when "E-4" is displayed.
(Cause: Focus gain (FGC) is set beyond the limit.)
Check if
(1) the waveform or voltage of the focus servo circuit is correct. (check the waveform or voltage.)
(2) the focus coil of the optical pickup is correct (around 15 ohms).
(3) the optical pickup returns to the normal state by exchanging the traverse deck.
Follow the below steps when "E-F" is displayed.
(Cause: All adjustments (TGC, FGC, TBC, FBC) are set beyond the limit.)
Check if
(1) the optical pickup returns to the normal state by exchanging the traverse deck.
(2) the waveform or voltage of the servo IC's are correct. (check the waveform or voltage.)
Note:
It is not always necessary to exchange the traverse deck when an error message is displayed.
Be sure to check if the circuit is defective or not before exchanging the traverse deck.
Note:
If any other disc than the test disc (SZZP1054C) is used, an error message may be displayed.
This is not a malfunction.
