Introduction
This chapter provides beeper and LED definitions, scanning techniques, general scanning instructions and tips,

Beeper Definitions
The scanner emits different beeper sequences and patterns to indicate its status. Table 2-1 defines beep
sequences that occur during both normal scanning and while programming the scanner.
