Red	A data transmission error or scanner malfunction occurred.

Scanning

The scanner can operate in two scanning modes: triggered mode and Auto-ScanTM mode. In triggered mode the trigger button must be pressed to emit the scanner laser in order to a scan bar code. In Auto-ScanTM 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-ScanTM on page 4-5.

•If the scanner is in triggered mode, scan Triggered/Auto-ScanTM on page 4-5 to switch to Auto-ScanTM mode.

•If the scanner is in Auto-ScanTM mode, scan Triggered/Auto-ScanTM on page 4-5 to switch to triggered mode.

NOTE When the scanner is not used for an extended period of time in Auto-ScanTM mode, it enters sleep mode. To wake the scanner, press the trigger button.

2 - 4 Symbol LS1203 Product Reference Guide

To scan a bar code:

1.Install and program the scanner (see Setting Up the Scanner on page 1-2). For assistance, contact the local supplier or Motorola Enterprise Mobility Support on page xiii.

2.Ensure all connections are secure. (See the host chapter for the scanner.)

3.Aim the scanner at the bar code.

4.If the scanner is in triggered mode, press the trigger button. (In Auto-ScanTM mode, no trigger button press is required. The scanner laser is in constant on mode.)

				Auto-ScanTM Mode
Triggered Mode

Figure 2-2 Scanning - Triggered and Auto-ScanTM Modes

5.Upon successful decode, the scanner beeps and the LED turns green. (For more information about beeper and LED definitions, see Table 2-1 and Table 2-2.)

NOTE Scan line lengths vary depending on the scan line width selected (see Scan Line Width on page 4-6). A full scan line width is the default. The medium scan line width is useful for scanning menus or pick-lists.

Aiming

On a typical UPC 100% bar code symbol, hold the scanner between contact and 7 inches from the symbol (see Decode Zones on page 2-6). Ensure the scan line crosses every bar and space of the symbol.

The scan line is smaller when the scanner is closer to the symbol and larger when it is farther from the symbol. Scan symbols with smaller bars or elements (mil size) closer to the scanner and those with larger bars or elements (mil size) farther from the scanner.

Do not hold the scanner directly over the bar code. Laser light reflecting directly back into the scanner from the bar code is known as specular reflection. Specular reflection can make decoding difficult.

NOTE Scan line lengths vary depending on the scan line width selected. A full scan line width is the default. The medium scan line width is useful for scanning menus or pick-lists.

For more information about scan line widths, see page 4-6.

Scanning 2 - 5

The scanner can be tilted up to 65° forward or back and achieve a successful decode (Figure 2-4). Simple practice quickly shows what tolerances to work within.
