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.
Scanning
The scanner can operate in two scanning modes: triggered mode and Auto-Scan
TM
mode. In triggered mode the
trigger button must be pressed to emit the scanner laser in order to a scan bar code. In Auto-Scan
TM
mode the
scanner laser is in constant on state and no trigger button press is required to scan a bar code.
To toggle between scanning modes, scan Triggered/Auto-Scan
TM
on page 4-5.
• If the scanner is in triggered mode, scan Triggered/Auto-Scan
TM
on page 4-5 to switch to Auto-Scan
TM
mode.
• If the scanner is in Auto-Scan
TM
mode, scan Triggered/Auto-Scan
TM
on page 4-5 to switch to triggered
mode.

normal and usually happens when the host cold boots.
