When scanning a single bar code, ensure that only the desired bar code is
within the field of view of the scanner.
Because imagers generally have a shorter depth of field than laser scanners, some
practise may be required to find the optimal distance from the types of bar codes
being scanned. Although the imager includes illumination LEDs, ambient light will
help the imager decode the bar codes, especially if the bar code is far from the hand-
held.
Important: Keep in mind that the imager scanner is a camera, and the LED
illumination is a flash. Glare can be an issue on reflective media
such as plastic coated bar codes, just as glare is an issue for photog-
raphers. When pointing at a shiny surface, either shift the bar code
to the side or top, or angle the bar code so that the glare reflects
away from the imager scanner.
Most imagers take several ‘snap shots’ of the bar code in order to
decode it. It is normal for the LEDs to flash two or three times. Hold
the unit steady between flashes to improve decode performance.
• Turn the hand-held computer on. Wait until the unit has booted
up completely.
• Aim at the bar code and press the scan key or the trigger. Hold the trigger
until a successful or failed scan result is obtained.
• When the scan button or trigger is pressed, a red, oval shaped light (the
framing marker) is displayed. Centre the framing marker in the field—
either in the centre of the bar code you want to scan or in the centre of the
area in which multiple bar codes are to be scanned.
The illumination LEDs will flash (typically several times) and a picture of the bar
code(s) is taken.
