TECHNICAL DATA ORBAN MODEL 5518
If you intend to replace parts, please read page 6-15. Please note that because sur-
face-mount parts are used extensively in the 5518, 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.
