Note If auto commands are being used, the communications time will vary slightly de-
pending on when the ID Tag reaches the Antenna’s communication area. When
calculating the proper ID Tag speed, add one page to the actual number of pages
being processed (e.g., use 2 pages if only 1 page is being processed) and calcu-
late the speed from this number of pages and the width of the communication
area.
