Documentation
Crown provides instruction manuals for every hardware and software product
that is in regular production. These are resources that usually provide the
answers. The most complete and accurate information possible is compiled in
these documents to assist you with installation and operation. These docu-
ments are usually product specific and in many cases do not cover complex
system level situations that you have to deal with. We also update our
documentation from time to time and continually strive to provide the best
information possible. If you keep old manuals for reference keep in mind that
new documentation may correct errors or provide additional information that
older manuals may not have. There may be other considerations as well such
as product changes.
Crown Technical Support Group: 1-800-342-6939/1-219-294-8200
A team of people at the Crown factory exists for the purpose of providing
technical assistance with Crown products. If you need help the Technical
Support Group is available. Normal business hours (8 am to 5 pm EST) are kept,
but if you are working on a major project and feel that after hours assistance may
be needed you may contact us to make special arrangements. If you are calling
about a problem you are having with the system it is much easier to help you
if you have taken the time to check available documentation. It is also very
helpful if you have serial numbers, software revision numbers, or other relavent
information handy when you call. If a hardware product is defective we will
assist you in getting the product repaired. Refer also to the Factory Service
section later in this chapter. If a software product is defective you should call
us to make arrangements to take care of the problem. With software there are
often special procedures that are beyond the scope of conventional hardware
service procedures.
STEP BY STEP IQ SYSTEM TROUBLESHOOTING
There are a few basic questions that must all be answered yes to prove that an
IQ System is operating properly. Does the software perform a Roll Call? Does
the software find and identify an interface at Roll Call? Does the software find
all components in the system at a Roll Call? Do all components remain in
communication with the computer after Roll Call? If the answer to each of these
questions is yes, then any problems you are having are probably in the audio
path or in the way that components are programmed. To learn how to set up
a component to get a desired result refer to the applicable chapter of the text
book or the software and hardware manuals associated with that component.
Figure 8 is a troubleshooting flow chart. It is impossible to cover every possible
problem, however most of the more significant possibilities are explored. The
following sections walk through the block diagram in greater detail.
