| The clock does not power up and the display is blank. | 
            The clock does not have power. Do:
             
              - Ensure the primary side of the DC power pack assembly is plugged into a live AC outlet. Ensure the secondary side of DC power pack assembly is plugged into the clock reader.
 
              - Test the outlet by plugging in another appliance.
 
              - Replace the power pack assembly.

            | After the initial power-up, the clock displays IP address, or the normal idle screen message is not displayed. | 
            The 6000 series clock does not have a clock program loaded. See Loading the clock program. | 
           
           
            | The clock is not communicating with the WBCS. | 
            The communication cable connecting the clock to the WBCS is defective or unplugged. Or the clock server is not running.
             
              - Verify that the cable is plugged into both ends.
 
              - Ethernet connections must have a wire length shorter than 328 wire feet (100 meters) connecting the clock to the Ethernet hub/switch.
 
              - Ensure the clock program is loaded and running on the host.
 
              - Ensure all communication parameters on the host and clock reader match.
 
              - Ensure the server running WBCS is on and the WBCS service is running.

            | Clock does not accept badge data. | 
            There are several possibilities: 
             
              - The bar code badge is not manufactured to proper specification. See the vendor's specifications for manufacturing criteria and verify.
 
              - The badge is being swiped in the wrong direction; ensure the media faces to the right (away from the keypad) when swiping.
 
              - The badge code format is not supported; ensure the badge code is among those supported. Supported codes include most standard bar code formats including UPCA, 128, 3 of 9, 2 of 5, Interleave 2 of 5 and more, as well as IATA Track I and ABA Track II magnetic stripe input (program dependent).
 
              - The badge reader requires cleaning; swipe a pre-moistened (isopropyl alcohol) cleaning card through the reader several times and retry a swipe.
 
              - The badge number does not exist. See Setting up employee badge numbers.
