Aiming Pattern
NOTE Scanning Direct Part Marks (DPMs) with the DS3407-DP (DPM) Digital Scanner: Due to the reflective
nature of some surfaces used with DPMs (see Figure 2-4), for best performance when scanning DPMs
with the DS3407-DP (DPM) digital scanner, tilt the scanner at an angle relative to the target (Motorola
recommends 25-45 degrees). For example, when scanning a 23 mil dot peen mark with the scanner set to
near focus, present the target between one and four inches from the nose of the scanner at a minimum tilt
of 30 degrees.
When scanning standard (non-DPM) bar codes with any configuration of the DS3407 digital scanner,
follow the standard aiming instructions described in Aiming.
