Diagnostic procedure
1. Unplug the AC power cord.
2. Replace R599 on the PNLB Assy with R569.
3. Plug the AC power cord.
4. Turn the unit ON and check each voltage.
Unplug the AC power cord after several seconds, because power will be forcibly supplied even if any voltage is abnormal.
(If abnormal voltage continues, the defective point may produce heat, which may be dangerous.)
5. If the voltage at any power IC is abnormal, the circuit that is connected to the power IC or the power IC itself may be defective.
6. Repair the detective part.
7. Replace R569 on the PNLB Assy with R599 (return R599 to its original position).

Player operation mode command
Play(Trace) / Pause
If it is in a stop state, it will set up and play. Moreover, if it is in a play state, whenever it will push a button, a pause and a play are carried out by turns.
Display a playing address in FL at present.
Note: In this mode, even if it inserts a disc, an automatic setup is not carried out.
Moreover, a play is not carrying out audio reproduction, but is tracing the signal side of a disc.
Trace a disc by a turn of four times speed in the play. The sound is not output.
Track Search F/R
Search a track displayed by a FWD / REV direction and do pause.
Error Rate Count
I measure an error rate from a present position doing a play/pause for about 10 seconds and display a measurement result in FL. Usually, a track to measure is made to search and this button is inputted from a pause state.
For example, it is displayed as "3.56E-4 O.K." etc.
If an error rate is less than 3.00E-3, it will be displayed as OK. If an error rate is larger than 3.00E-3, it will be displayed as NG.
Measurement with the managed disc at the time of factory shipments is a premise.
The product does not judge whether they are inferior goods at the time of service.
Eject
A disc is ejected.
Mode Change
