1. For pickup unit(CXX1286) handling, please refer
to"Disassembly"(see page 73).
During replacement, handling precautions shall be
taken to prevent an electrostatic discharge(protection

2. During disassembly, be sure to turn the power off
since an internal IC might be destroyed when a con-
nector is plugged or unplugged.
3. Please checking the grating after changing the ser-
vice pickup unit(see page 60).
