NEO Hand-Held with Windows Mobile 6.1 Classic User Manual
When the scan is successful, the bar code data is displayed on the screen until the scan
button (or pistol trigger) is released, but only if
Scan Result
is turned on in the
Options
tab
discussed in the previous paragraph.

Troubleshooting
If the scanner is not working, investigate the following:
•
Check that the bar code symbology being scanned is enabled for the hand-held you are
using. Check any other parameters that affect the scanning procedure or the bar code.
•
Check the bar code to make sure it is not damaged. Try scanning a different bar code to
verify that the problem is not with the bar code.
•
Check that the bar code is within the specified decode zone. Refer to “Scanner/Imager
Specifications” on page 233 for details.
•
Does the hand-held display the warning without scanning? This suggests a hardware
problem in the hand-held.
•
Is the laser beam scanning across the bar code?
•
Once the scan beam has stopped, check the scanner window for dirt, fogging or damage.

Bluetooth
Peripherals
NEOs equipped with
Bluetooth
radios make it possible to communicate with a variety of
Bluetooth
peripherals, including GSM/GPRS handsets, scanners, printers, and so on.
The range of the
Bluetooth
radio is limited to approximately 10 meters.
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 NEO 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 hand-held 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 net-
work, Psion Teklogix recommends using
Bluetooth
peripherals that have low transaction
rates (such as printers and scanners).
Refer to “Bluetooth Setup” on page 177 for information about setting up your
Bluetooth
devices for communication. In addition, review the manual shipped with your
Bluetooth
device to determine the method used to pair with NEO host.
