2.1.6 Bar Code Scanner
The bar code scanner is located on the left side of the instrument (Figure 2-4). When
activated, it illuminates a bar code light so that the bar code on the white assay
pouch can be presented by the user to be scanned, decodes the bar code, and
transmits the information to the instrument software. The instrument software
identifies the assay device expiration date and lot information. See section 6.4,
Procedure number 10 for additional information.
