Bluetooth Wireless Tips
Xplore Technologies® and its Bluetooth® partners have worked to ensure a positive experience
with this technology and to ensure Bluetooth interoperability. In doing so, we have found the
following issues:
• Interference
If you’re running Bluetooth and Wi-Fi® at the same time, interference can affect the
Bluetooth performance. This is most noticeable if:
– You try to transfer large amounts of data, such as with file transfers.
– Several Bluetooth devices are operating in an office simultaneously.
• Speech Recognition
Bluetooth audio has not been fully developed for speech recognition. Therefore, for
speech recognition, we recommend that you not use a Bluetooth wireless headset.
• Disconnection 
Some Bluetooth devices disconnect when they go into power-saving mode. Most devices
automatically reconnect when they become active again.
• Incompatible drivers
If you attempt to install other wireless headset or other audio drivers, such as Bluetooth or
USB, over the Tablet
PC audio drivers, a malfunction of the Tablet PC audio system might
occur, because the drivers might not be compatible.
• Interoperability
If you are having issues with interoperability of Bluetooth devices, contact the
manufacturer of your Bluetooth device and check its compatibility with the Bluetooth
software installed on your Tablet
PC.
• Security
Bluetooth devices use a passkey to create a secure connection between the Tablet PC and
the Bluetooth device. Although the passkey exchange helps to secure your data,
Bluetooth wireless technology shouldn’t be considered completely secure.
Mobile Broadband with GNSS Issues
I can’t connect to a mobile broadband network.
• A mobile broadband network requires you to have a data plan from a cellular network
provider.
• You might need a SIM card from your network provider. (See INSERTING AND REMOVING A
SIM CARD on page 52.)
• For more details, see CONNECTING TO A MOBILE BROADBAND NETWORK on page 26.
I changed my SIM card and now I can’t connect to my mobile broadband network.
• The tablet should be shut down when changing or inserting the SIM card. Restart the
tablet to enable the SIM card.
