a solid deal - quick and without any problems.
I life in europe - with downloads no loosing time
once again
 ;
got exactly what i ordered in a very timely manner. will use again for other manuals
;
I'm happy. Good quality. Very helped me with my work..............................
;
This is the second Manual I have ordered from owner-manuals, I give it five stars because it is exactly what I expected given the age of the equipment. So the contents look a bit aged and the pictures a bit grainy, it fulfills my needs and I am glad I can still get hold of them.

thank u so much for this manual that was so cheap that i thought it was a scam but i gambled anyway because it was too good of a deal to pass up and behold,the manual has everything and details of everything even the screws and im still amazed and very happy with my manual .so take my word and jump on it before they realize how cheap they selling thier manuals..thank you so much for taking time to read my thoughts

1.2.3 Tracking / Slider Servo
ATB: For phase differential TE (use for DVD), the tracking balance compensation is achieved by outputting the offset from the TBAL output at pin 44 of the digital servo IC, and by biasing the charge pump resistor for phase-difference error of RFIC. For 3-beam TE (use for CD), the tracking balance compensation is achieved by adjusting the gain balance of A and C in RFIC with the voltage of RFIC-pin 30. The difference is detected by processing TE at pin 32 of IC 201 with an internal digital equalizer. TDO: In addition to the servo output, the lowband components, such as the kick-brake for jump, are added for TDO output. SLDO: The low-band components of TE are processed by the internal digital equalizer, and deadband is added for SLDO output. The offset voltage for pickup movement is also included in the SLDO output.

1.2.4 SPINDLE SERVO
For a CD, the RF signal output from pin 46 of the RF IC is converted to binary in IC201. By comparing the binary value with the reference CLK (clock), the SPDL ERR signal is output from pin 46. � SPDL SERVO

46
For a DVD, the SPDL ERR signal is generated from the PWM signal output from LSI-��. Upon receiving this signal via pin 29, IC201 also outputs it from pin 46, switching from the CD SPDL ERR signal.
