Additional FunctionsProduct Reference Guide 3-9Scanner and Scale ResetThe reset procedures and indicators are identical for scanner and scanner/scale models. As with any electronic equipment, it is sometimes necessaryto reset the electronics. The reset procedure allows you to initiate a resetcommand to the scanner. This may be necessary if the POS terminal hasbeen switched off or the store system has been reset while the unit is on.Reset can also be used to initiate and run the unit’s internal Selftest rou-tine.Pressing and holding the Volume/Tone Push Button for approximatelyeight seconds initiates a reset, which is sounded by a rapid number ofbeeps. If the motor had been spinning, the lamps will blink while themotor spins down. At that point, the motor will spin back up and thescanner will continue to run the Selftest diagnostics. For more informa-tion, see the topic, Power-Up/Selftest & Pre-Operation, earlier in thischapter.Scale AdjustmentsThe scale allows two user adjustments: zeroing and calibration. The first,and most frequently performed, is ‘zeroing’ the scale. This operation resetsthe scale’s “at rest” reading to zero which must be within the range of - 0.2pounds (- 0.09kg) to +0.6 pounds (0.27kg) since the last calibration.While the ‘at rest’ reading remains within the zero range, the scale willautomatically adjust itself to true zero. The scale also automatically zerositself on power-up if the weight present on the scale is within these definedlimits.Zeroing the ScaleThe zeroing operation may be performed by checkers and other store per-sonnel. Pressing and releasing the Scale Zero Push Button should returnthe scale to Normal Operation. If the zero point moves out of the zerorange due to debris accumulation or other causes, pressing the Scale ZeroPush Button will not reset the zero point. In this case the weigh plattermust be cleaned, debris chutes cleared of debris or the scale must be recal-ibrated.
