I am unclear what you mean by service manual adjustments. The model that I have is the MZ-M100. Are there any adjustments that can be made to improve battery charging.
Also, here's another question about this model. I do not recall getting an AC adapter when I bought this, although I am sure that I did, and perhaps it's even in the house somewhere. Anyway, the manual says do not use any adapter except the one provided. The package and the manual, as best I can tell, don't tell you anything about the adapter and have no real pictures of it. If I do have it, how can i tell which one it is. And if I don't have it, can I use other Sony MD adapters that I have?
Any help would be appreciated,
Sue
