NOTE: You MUST have a TSS revision of 3.6.4 or GREATER to use 2004 and newer downloadable inventory. Revisions at or beyond 3.6.4 upgrades the character length of the inventory's MAKE / MODEL from 10 characters to 30, thus accommodating the new 2004 and newer MAKES / MODELS that exceed 10 characters. To locate the revision version your are currently on, look in the upper left corner of the TSS Main Menu. The program's current revision numbers and it's enhancements are found upon the What's New tab on the www.tsshelp.com page. If an update is necessary, select AutoUpdate from the TSS Start button, lower left of TSS Main Menu, and select the desired update, Standard or Beta.
