The manual was missing 2 pages but when I presented the problem to the company they made every attempt to get the 2 pages to me, when they couldn't they refunded my money. A very pleasing and easy transaction. The manual they provided was the original, it was concise and to the point. I plan to do business with this company again when should the need arise.
 ;
The owners manual is very good. all my how to questions were answered in detail.
;
Irrespectively of this manual exist only germany language, it's useful - although i need some additional task to translate: My english is bad, but usable - but i really dont speak germany. :)
;
Excellent service from this company (including a total refund on an earlier purchase when through no fault of the company the manual was incomplete). I have purchased several manuals which I have been very satisfied with, as I am with this one. Highly recommended.
;
It was easy to order and received exactly what I needed. Only complaint would be the 24 hours you have to wait.

Maintenance of laser pickup
(1) Cleaning the pick up lens Before you replace the pick up, please try to clean the lens with a alcohol soaked cotton swab. (2) Life of the laser diode When the life of the laser diode has expired, the following symptoms will appear. The level of RF output (EFM output:amplitude of eye pattern) will below.
Replacement of laser pickup
Turn off the power switch and,disconnect the power cord from the AC OUTLET.
Replace the pickup with a normal one.(Refer to "Removing the CD pickup" on the previous page)
Is the level of RF OUT under 1.25V 0.22Vp-p?
NO Replace it.
Plug the power cord in,and turn the power on. At this time,check that the laser emits for about 3 seconds and the objective lens moves up and down. Note: Do not observe the laser beam directly.
YES O.K Play a disc.
Check the eye-pattern at the "RF" test point.
Finish.
(3) Semi-fixed resistor on the APC PC board The semi-fixed resistor on the APC printed circuit board which is attached to the pickup is used to adjust the laser power. Since this adjustment should be performed to match the characteristics of the whole optical block, do not touch the semi-fixed resistor. If the laser power is lower than the specified value,the laser diode is almost worn out, and the laser pickup should be replaced. If the semi-fixed resistor would be adjusted when the pickup operates normally,the laser pickup may be damaged due to excessive current.
