Optonica SM-4545 (=SM-4000) manual uploaded

Hi emreitcz,

I've just bought the service manual for the Optinica SM-4545. This model was sold outside the USA as the SM-4000 (wich is the model i own). I don't know what the exact difference is between the SM-4000 and the SM-4000U but maybe this manual is of any use for you. It should be on the site in a while.
