LED Definitions
In addition to beeper sequences, the digital scanner communicates with the user using a two-color LED display.
Table 2-2 defines LED colors that display during scanning.
Host Specific
USB only
Four high beeps Digital scanner has not completed initialization. Wait several
seconds and scan again.
Digital scanner gives a power-up beep after
scanning a USB Device Type.
Communication with the bus must be established before the digital
scanner can operate at the highest power level.
This power-up beep occurs more than once. The USB bus may put the digital scanner in a state where power to
the digital scanner is cycled on and off more than once. This is
normal and usually happens when the host PC cold boots.
