to"Disassembly"(see page 88).
During replacement, handling precautions shall be
taken to prevent an electrostatic discharge(set the
short switch of the pickup unit to the SHORT side).
3. During disassembly, be sure to turn the power off
since an internal IC might be destroyed when a
connector is plugged or unplugged.
4. Please adjusting the skew after changing the pickup
unit(see page 63).
