Troubleshooting
226 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.
7.9.3 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.
7.10 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.
