Aiming - Motorola Symbol DS3407 Product Reference Manual

Aiming

Hold the digital scanner between two and nine inches (depending on symbol density; see
2-9) from the symbol, centering the aiming pattern cross hairs on the symbol.
The aiming pattern is smaller when the digital scanner is closer to the symbol and larger when it is farther from the
symbol. Scan symbols with smaller bars or elements (mil size) closer to the digital scanner, and those with larger
bars or elements (mil size) farther from the digital scanner.
The digital scanner can also read a bar code presented within the aiming pattern but not centered. The top
