•

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 205 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.

NEOs equipped with Bluetooth radios make it is 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 102 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 the NEO host.
