To scan a bar code:

1.

Install and program the scanner (see

). 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-Scan

TM

mode, no trigger button press is

Upon successful decode, the scanner beeps and the LED turns green. (For more information about beeper

Table 2-1

and

Table 2-2

.)

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.

Figure 2-3

Acceptable and Incorrect Aiming

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.
