Motorola's parts order line is 1-800-422-4210. The people at this hot line wanted $11.55 for the MITREX manual and took my credit-card order right away. My local Motorola parts depot quoted $25 for the same manual, did not have it in stock, and then could not figure out what the shipping cost would be so they suggested I drive out to the depot and pick it up when they got it. From this experience I would suggest that you use the 800 number for parts. The part number for the MITREX UHF manual is 68-81045E75, $11.55 Motorola's Parts Identification Hotline number is 708-538-0021.
