following displays:
[Scan Slower!] or [Scan Evenly!] or [Scan Faster!]
indicating that the scan was either too fast, too uneven/erratic or too slow for
proper data collection. A practiced, more deliberate and smooth rescan should

touching the symbol surface. Practice helps! A successful measurement will be
signaled by beeping, a blinking green (pass) or red (fail) LED and the display
showing results such as:
