I thought that I had set up the turntable properly, but I clearly have not. When I try to play a record and position the needle over the record, the needle slides to the right, off of the record. How do I fix this? The counterweight or something needs to be adjusted, but if I have it float level with the record, it slides off, if I have it set up so that it rests as low as it can go, it is too low. The manual is of no use to me. Thanks in advance.
