Beeper Definitions
The scanner issues different beep sequences and patterns to indicate status. Table 2-1 defines beep sequences that occur
during both normal scanning and while programming the scanner.
LED Definitions
In addition to beeper sequences, the scanner communicates with the user using a two-color LED display. Table 2-2
defines LED colors that display during scanning.

Scanner gives a power-up beep after scanning a USB Device
Type.
Communication with the bus must be established before the scanner can operate
at the highest power level.
This power-up beep occurs more than once. The USB bus may put the scanner in a state where power to the scanner is cycled
on and off more than once. This is normal and usually happens when the host cold
boots.
