b. Illustrations-Listing. Only those parts coded “O”, “F” in the third position of the SMR code are listed in the
tabular listing. Only illustrations containing unit and direct support authorized items appear in this manual.
c. National Stock Numbers. National Stock Numbers (NSNs) that are missing from “P” source coded items
have been applied for and will be added to this TM by future change/revision when they are entered in the Army
Master Data File (AMDF). Until the NSNs are established and published, submit exception requisition to: US Army
Communications-Electronics Command and Fort Monmouth, ATTN: AMSEL-LC-COM-R-SR, Fort Monmouth, NJ
07703-5023 for the part required to support your equipment.
d. Serial Number Effectivity. When part numbers of spare/repair items are not the same for all serial numbered
equipment, of the same model, serial number effectivity will identify the correct parts to be ordered. The serial
number effectivity that appears in the tabular list is the serial number effectivity for the next higher assembly. If a
figure has more than one model, both models will be shown, each with it’s own serial number effectivity. If a part
in the tabular list does not have a serial number effectivity then that part can be used in any model. Whereas, if a
part has a serial number effectivity, it is model unique and can only be used in the model marked with the same
serial number effectivity.
6. How to Locate Repair Parts
a. When National Stock Number or Part Number is Not Known.
(1) First Using the table of contents, determine the assembly group or subassembly group to which the
item belongs. This is necessary since figures are prepared for assembly groups and subassembly groups, and
listings are divided into the same groups.
(2) Second. Find the figure covering the assembly group or subassembly group to which the item belongs.
(3) Third. Identify the item on the figure and note the item number.
(4) Fourth. Refer to the Repair Parts List for the figure and item numbers. The NSNs and part numbers are
on the same line as the associated item numbers.
b. When National Stock Number or Part Number is Known.
(1) First. If you have the national stock number, look in the STOCK NUMBER column of the National Stock
Number Index. The NSN is arranged in national item identification number (NIIN) sequence (see paragraph 4a).
Note the figure and item number next to the NSN.
(2) Second. Turn to the figure and locate the item number. Verify that the item is the one you are looking
for.
