Note: When scanning multiple bar codes, ensure that all of the desired bar codes are
within the field of view of the scanner. It is possible that even when all bar codes are
within the field of view, not all of them will be decoded. Only successfully decoded
bar codes are passed to the application program. The application program then
issues a warning, asking that you scan the missing bar codes.
When scanning a single bar code, ensure that only the desired bar code is within the
field of view of the scanner.
Because imager scanners 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 illumina-
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 suc-
cessful 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.

Bluetooth Peripherals

It is possible to communicate with a variety of Bluetooth peripherals, including GSM/GPRS
handsets, scanners, printers, and so on. The range of the Bluetooth radio in Omnii is limited
to approximately 10 meters (32 ft.).
Psion Teklogix provides built-in support for:
tion is a flash. Glare can be an issue on reflective media such as plastic
coated bar codes, just as glare is an issue for photographers. 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.
