Quick Check® 600/800 Series User’s Guide 3 - 11• Beeper Pitch (raise or lower)• Extended Accuracy• Decoding direction (both ways or forward only)Beeper PitchYou can change the pitch of the verifier’s beeper. Higher pitches seem to soundlouder. You can also turn off the tone. The default is 16. The range includes Offand 1 through 31.Extended AccuracyThe Extended Accuracy setting is the number of scans of the same symbol,taken at the same path in the symbol, that yields the scan grade.• With Extended Accuracy on, individual parameter measurements and resultsare averaged over successive scans of the symbol. Using the extendedaccuracy mode greatly reduces reading variability due to variations inscanning motion and minor scan path variations. When Extended Accuracyis on, you select the number of scans for the averaged result from 2 through10, 12, 15, 20, 30, 50 and 100.• When Extended Accuracy is off (set to one), each scan of the symbol givesthe measured results. The default is Extended Accuracy turned off.When you scan a symbol with Extended Accuracy on, a numeric counter appearson the display telling you how many additional scans of the same path you mustobtain. After you satisfy the setting, the scan grade appears. If you do not scanthe same symbol within five seconds, the unit assumes you do not want to satisfythe Extended Accuracy setting you chose and displays the scan results from thatindividual scan. If you scan a different symbol after your first scan, the ExtendedAccuracy counter resets.For further discussion and comparison of scan grade to symbol grade, refer toChapter 4, Reviewing Scan Data.Decode DirectionYou can set the Quick Check 600/800 Verifier to read bar code symbols from left-to-right, called “forward only,” or from either direction, called “Both Ways.” TheBothWays setting (default) makes scanning easier and more flexible thanforward-only scanning.♦ To change the scanning options:1.
