TECHNICAL DATA
Schematics and Parts Locator Drawings
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
improvements or production changes since the publication of this manual.
If you intend to replace parts, please read page 6-15. Please note that because sur-
face-mount parts are used extensively in the 5500, 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 re-
placed in the field.
