- Service Precautions
1. For pickup unit(CXX1305) handling, please refer
to"Disassembly"(see page 80).
During replacement, handling precautions shall be
taken to prevent an electrostatic discharge(protection
by a short pin).
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 72).
4. In the correct orientation, characters can be seen
when viewed from the product rear side.(A wind
blows.)
5. Since the RCA, IP and ASL cords are fixed with lock
tie, the lock tie needs to be cut off at the time of dis-
assembly. At the time of assembly, new lock tie is
needed.
6. When operating with large output power, the heat
sink becomes very hot. Be careful not to touch it. In
particular, be careful of the heat sink on the bottom
of a product.
