Notes on chip component replacement
· Never reuse a disconnected chip component.
· Notice that the minus side of a tantalum capacitor may be
damaged by heat.
Flexible Circuit Board Repairing
· Keep the temperature of soldering iron around 270°C
· Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
· Be careful not to apply force on the conductor when soldering

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
The flexible board is easily damaged and should be handled with
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION
Carry out the "S curve check" in "CD section adjustment" and check
that the S curve waveform is output several times.

HOW TO OPEN THE DISC TRAY WHEN POWER
SWITCH TURNS OFF
When removing the disc tray, high torque is necessary to turn the
ejection cam on the bottom surface. Therefore, the screw thread is
easily damaged. To prevent this damage, turn it carefully.
1 Turn the cam in the direction of the arrow.
2 Pull-out the disc tray.

· CLEANING THE OPTICAL PICK-UP
In cleaning the lens, do not apply an excessive force
As the optical pick-up is vulnerable, application of
excessive force could damage the lens holder.
In cleaning, do not use a cleaner other than exclusive
cleaning liquid. (KK-91 or isopropyl alcohol)
Wipe the obujective lens spirally from center toward
outside. (See Figure A)
· DISC TRAY LOCK
The disc tray lock function for the antitheft of an demonstration
disc in the store is equipped.
Setting Procedure :
A button or the H button of the main unit or 1
button on the remote commander to turn the set on.
Press two buttons of DISPLAY and
simultaneously for two seconds.
The message "LOCKED" is displayed and the tray is locked.
Releasing Procedure :
Press two buttons of DISPLAY and
simultaneously for two seconds again.
The message "UNLOCKED" is displayed and the tray is
Note : When "LOCKED" is displayed, the tray lock is not released
by turning power on/off with the POWER button.
· MOVEMENT CONFIRMATION BY THE REMOTE
CONTROLLER OF OTHER MODELS
Signal code of the attached remote controller may vary in the
generation of CD/DVD player.
The signal code of FUNCTION, BAND, ST/MONO and
MEMORY is different with the remote controller for DAV-S400
and the remote controller for DAV-S550/S880/C770/C990.
Be careful when you confirm by the remote controller of the different
