Product Reference Guide 2-5Since the scanner reads labels on all four sides plus the bot-tom, there is no need to turn a bar code toward either of thescanner windows.Develop efficient scanning motions, not necessarily fasterhand movements. Simply slide the item across the scanner’shorizontal window with as little orientation motion as neces-sary.Leave items in an upright position; do not lift and tilt.Learn how the scanner functions and where the scanning areais located.Do not favor either the vertical or horizontal window; slideitems across the scanner in their natural orientations on thecheckstand as much as possible.Site Preparation OverviewConsider the following factors before installing the scanner/scanning-scaleand its optional Remote Scale Display.Ventilation Requirements. The scanner operates without the use of aventilation fan. As long as there is adequate convective air flow and nomajor heat producing equipment in close proximity, the unit’s housingprovides adequate heat dissipation. The air temperature in the checkstandaround the scanner must not exceed 104°F (40°C).Service Access Requirements. Routine operations such as ‘zeroing’and calibration do not require removal of the scanner from the checkstandor disassembly of the product. The installer should plan service access forthe AC/DC Power Supply and cables.Recommended Power Installation. Since the typical grocery environ-ment includes conveyor belts and electric motors, care should be taken toensure that the scanner has a supply of “clean” power (power withoutexcessive electrical noise). A wiring diagram shows the recommended wir-ing that will provide the scanner with a “clean” source of power. Refer toFigure 2-4.
