ELECTRICAL ADJUSTMENT ADJUSTMENT POINT (Component Side) Precautions before Adjustment 1. Before playing the test tape back, thoroughly demagnetize the

33、 heads, capstan and similar metal parts using an eraser PU03 as the test tape-recorded tone is easily erased. 2. Do not place the test tape on any measuring instrument. 3. Do not put the test tape near a place where the eraser is used. 4. Method of Demagnetization: -Turn the eraser power switch on a

34、t a remote position far away from the heads. Bring the eraser close to the heads, capstan and other parts to be demagnetized. and move it up and down four or five times to demagnetize. Slowly separate the eraser far away from the parts, and turn the power switch off. 5. Tools to be used shall not be

35、 magnetized. It is recom- mended to demagnetize tools occasionally using a demag- netizer. 6. Do not turn semi-fixed resistor more than needed. 7. Do not apply locking bond excessively.
