CHAPTER 2 SCANNING
Introduction
This chapter provides beeper and LED definitions, scanning techniques, general instructions and tips about
scanning, and decode ranges.
Beeper and LED Definitions
The linear imager scanner issues different beep sequences/patterns and an LED display to indicate status.
Table 2-1 defines beep sequences/patterns and LED displays which occur during both normal scanning and
while programming the linear imager scanner. (Also seeTable 1-3 on page 1-12 and Table 1-4 on page 1-13 for
charging and battery reconditioning LED indicators.)
