Ikôn Rugged PDA (Windows CE 5.0) User Manual 245
• Turn the Ikôn on. Wait until the unit has booted up completely.
• Aim at the bar code and press the scan key or the button. Hold the button until a success-
ful or failed scan result is obtained.
• When the scan button is pressed, a red, oval shaped light (the framing marker) is dis-
played. 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.
6.12 Bluetooth Peripherals
The Ikôn is equipped with a Bluetooth radio, making it is possible to communicate with a
variety of Bluetooth peripherals, including GSM/GPRS handsets, scanners, printers, and
so on.
Psion Teklogix provides built-in support for the Bluetooth peripherals listed below.
• GSM/GPRS universal handset.
• Bluetooth printer.
• Bluetooth headset.
Keep in mind that Bluetooth and IEEE 802.11b/g radios both operate in the 2.4GHz band.
Although the Ikôn includes features to minimize interference, performance of the system
will not be optimal if you use both radios simultaneously. Typically, when both radios
operate in the Ikôn at the same time, they cannot transmit simultaneously—this has a nega-
tive impact on overall system throughput. To minimize the impact on the backbone 802.11g
network, Psion Teklogix recommends using Bluetooth peripherals that have low transaction
rates (such as printers and scanners).
Important: Keep in mind that the imager scanner is a camera, and the LED illumina-
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.
