OVERVIEW OF SYSTEM COMPONENTS - 2VerifyNow System User Manual Page 16 14340.JFigure 2-3 Power Switch2.1.6 Bar Code ScannerThe bar code scanner is located on the left side of the instrument (Figure 2-4). Whenactivated, it illuminates a bar code light so that the bar code on the white assaypouch can be presented by the user to be scanned, decodes the bar code, andtransmits the information to the instrument software. The instrument softwareidentifies the assay device expiration date and lot information. See section 6.4,Procedure number 10 for additional information.Figure 2-4 Bar Code Scanner and Fan2.1.7 FanThe instrument is equipped with an exterior fan vent next to the bar code scanner tocool the internal electronic components. Avoid placing equipment adjacent to the fanthat obstructs airflow. Periodic cleaning of the fan filter may be performed to avoidoverheating of the instrument. See section 9.3 for fan filter replacement instructions.2.1.8 Printer (Accessory)The printer is an optional accessory to the instrument. The printer enables anoperator to print assay results, QC results, and instrument usage statistics. Seesection 8.8 for instructions on enabling the printer.2.2 Assay DeviceThe VerifyNow System uses disposable assay devices to conduct the test.
