TECHNICAL DATA Orban Model 8400
These drawings reflect the actual construction of your unit as accurately as possible. Any
differences between the drawings and your unit are probably due to product improve-
ments or production changes since the publication of this manual.
If you intend to replace parts, please read page 6-14. Please note that because surface-
mount parts are used extensively in the 8400, few parts are field-replaceable. Servicing
ordinarily occurs by swapping
circuit board assemblies. However, many vulnerable parts
connected to the outside world are socketed and can be readily replaced in the field.
