- Service Precautions
1. For pickup unit(CXX1305) handling, please refer
to"Disassembly"(see page 109).
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 93).
4. You can't recover the data if the HDD should break
for some reason.
5. Be careful to handle HDDs (as HDD navigation sys-
tems).
6. An external power supply box is used along with the
unit. Customers may consult their dealers without
bringing the box.
7. You can't play your data with any HDD or product
other than the original one, because each product
has its ID (CXK2000EN) for protecting copyrights.
Please use both of the ID and the data in the HDD as
paired with each other. (For example, if you
exchange the digital units because your unit has
defects, remove IC3305: CXK2000EN from the defec-
tive unit and install it in the new unit for use.)
