• Switch the EP10 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

The EP10 is equipped with a Bluetooth radio, making it 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 EP10 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 EP10 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).

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.
