Note that “u” appears in most cases instead of the correct symbol “μ” whenever a “micro” is required. Electronic
parts list data, when imported by our PC publication program, allows us to substitute the correct “μ” when
checking and editing.
3.6 PARTS LISTS
Parts lists for all assemblies in the transmitter are provided on CD-ROM, in PDF format. The CD-ROM is packed
inside the transmitter cabinet for shipping.
Parts lists are generated in a hierarchical structure, beginning with major assemblies, then the subassemblies of
each major assembly, and so forth.
3.6.1 Production Changes
From time to time, it may become necessary to make changes in the equipment described in this manual. Such
changes are usually made either to provide improved performance or to accommodate component substitutions.
