�� In the case of smaller amplitude, for adjustment, loosen �� the two screws #541 and then shift the MR head position �� as shown in the right figure. �Note�During adjustment, prevent the magnetic tape and MR �head from touching the magnetized driver bit, or the magnetic �data may be damaged. � �Reference� �� In case the amplitude of either CH1 or CH2 seems smaller, one of the two screws #541 may be loosened. �� Then, check the screws. In case the screws are fully tightened, the MR head may be troubled. Then, be sure to �� replace the MR head unit B15 and adjust it again.
