Important Information - HHB CDR-882 DualBurn Service Manual

1 Important information

This service manual is written for the use of trained service personnel only. Disassembly
of the CDR-882 DualBurn by an untrained operative could cause severe damage to the
unit, and will invalidate the CDR-882 DualBurn warranty.
It is essential that all normal electrostatic discharge (ESD) protection procedures are
carefully followed. Damage caused by ESD will not be covered by any warranty. During
reassembly, check that all cables are reconnected and are in the correct sockets.
This manual contains sections on disassembly/assembly, firmware updates and known
faults. Throughout this manual, part numbers are enclosed in square brackets (for example
[P8202]).
Please note that only a few component parts are available for the printed circuit boards
(PCB) as changing a majority of the PCB components is not considered practical for field
service. If faults occur, it is likely the whole PCB will have to be replaced.
Tools
Normal workshop tools for work on small electronic assemblies are required.
Notes
For your own safety, the mains power cord should be removed before disassembly takes
place.
No part of this manual may be reproduced or copied.
