Service Access
When routing and installing the cable(s) and power supply, make sure to leave access that these components may be swapped easily without the need to remove the unit from the checkout counter.
When changing the StratosSWAP optics engine modules, removing the unit completely from the checkout counter is recommended.
When calibrating or zeroing the scale, do not remove the unit from the checkout counter. Refer to the Scale Operation Section of this guide for detailed instructions on zeroing and calibration.
Power Installation
The Power Supply (AC/DC) should be connected to an AC outlet that is free of electrical noise (clean). A qualified electrician can determine the amount of electrical noise on the AC line. See additional information on power installation and restrictions under the Installation: Interface section of this manual.
Note: Using a switched AC outlet is recommended. The switch should be located on the operator’s side of the checkout counter in close proximity to the MS2420 scanner to facilitate calibration and service of the unit.
Checkout Counter Layout Considerations
When placing a scanner in a checkout counter, the following factors should be considered.
Items should flow at a distance to the operator that maximizes comfort. The operator should not need to stretch or strain to reach for and scan packages.
The MS2420 can scan a bar code on five sides of a package. The packages should flow into the scan area that provides the maximum reading performance. No lifting or orientation of the items is necessary. A properly placed item diverter can maximize the flow of packages.
