This is an excellent handbook. We had no information on the appliance until we obtained this and are now able to use the appliance to its full potential. Strongly recommended.
The Owner's manual was very helpful. The WEGA is about 35 years old and needed repair.
Your Website is pretty good und easily to handle.
Thank You

My first manual from Owner-Manuals.com but not the last! I am very satisfied with the easy ordering and promt delivery of a manual I did not find anywhere else.

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.
