Bluetooth Peripherals; Digital Camera - Psion EP10 User Manual

Because imagers generally have a shorter depth of field than laser scanners, some practise may be re-
quired to find the optimal distance from the types of bar codes being scanned. Although the imager in-
cludes illumination LEDs, ambient light will help the imager decode the bar codes, especially if the bar code
is far from the EP10.
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 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.
• 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 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.

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 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 802.11a/b/g/n 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 negative impact on overall system throughput. To minimize the impact
on the backbone 802.11g network, Psion recommends using Bluetooth peripherals that have low transac-
tion rates (such as printers and scanners).
Refer to "Bluetooth Setup" on page 105 for information about setting up your Bluetooth devices for com-
munication. In addition, review the manual shipped with your Bluetooth device to determine the method
used to pair with the EP10 host.

Digital Camera

Important: The EP10 is equipped with a digital camera that can take still pictures or short
video clips. Refer to Section 4.10 on page 68 for details about using the camera.
The Pictures & Videos applet allows the operator to activate the camera for still shots or video clips. It also
provides a number of tools to crop photos, adjust picture contrast and brightness, zoom in and out of
photos, and save your adjustments.
Important: The "Pictures & Videos" program can only display .bmp or .jpg formats. Photos in
other formats will need to be converted on your PC before they can be transferred
to the EP10 hand-held.
