NOTES ON HANDLING THE OPTICAL PICK-UP BLOCKOR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostaticbreakdown because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.
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 270C during
repairing. 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
or unsoldering.
UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARKUnleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higher than
ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set to about350 C.Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful! Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow) thanordinary solder so use caution not to let solder bridges occur suchas on IC pins, etc.
Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder may alsobe added to ordinary solder.
This appliance isclaassified as a CLASS 1LASER product. Thislabel is located on therear exterior.
NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused onthe 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 component in this product is capableof emitting radiation exceeding the limit forClass 1.

the BD49 board.2. Press the I/1 button to turn the power on.3. Load the disc (LUV-P01) and playback the number nine track.4. Press the hH button. (Becomes the 1 track jump mode.)5. Confirm that the level B and A (DC voltage) on the oscilloscope
waveform.
Connecting Location:
Note:1. CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.2. Use LUV-P01 (Part No. 4-999-032-01) unless otherwise indicated.3. Use an oscilloscope with more than 10MW impedance.4. Clean the object lens by an applicator with neutral detergent when the
signal level is low than specified value with the following checks.
S-CURVE CHECK
Procedure :1. Connect an oscilloscope to TP68 (FE) and TP73 (DVC) on
the BD49 board.2. Press the I/1 button to turn the power on.3. Load the disc (LUV-P01) and actuate the focus search. (In
consequence of open and close the disc tray, actuate the focussearch)
4. Confirm that the oscilloscope waveform (S-curve) issymmetrical between A and B. And confirm peak to peak levelwithin 2 0.5 Vp-p.
Note: Try to measure several times to make sure than the ratioof A : B or B : A is more than 10 : 7.
Take sweep time as long as possible and light up thebrightness to obtain best waveform.
RF LEVEL CHECK
Procedure :1. Connect an oscilloscope CH1 to TP71 (RFDC), CH2 to TP72
(RFAC) and TP73 (DVC) on the BD49 board.2. Press the I/1 button to turn the power on.3. Load the disc (LUV-P01) and playback the number nine track.4. Confirm that oscilloscope waveform is clear and check if RF
signal level is correct or not.

UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size)
: LEAD FREE MARKUnleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higher than
ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set to about350 C.Caution: The printed pattern (copper foil) may peel away if the
heated tip is applied for too long, so be careful! Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow) thanordinary solder so use caution not to let solder bridges occur suchas on IC pins, etc.
Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder may alsobe added to ordinary solder.
Note: The components identified by mark 0 or dotted linewith mark 0 are critical for safety.Replace only with part number specified.
