• Disconnection—Some Bluetooth devices will disconnect when they go into power-
saving mode. Most devices will 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 may occur because the drivers may not be compatible.
• Interoperability—If you are having problems 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 should not be considered completely secure.

external speakers disables the built-in speaker.
• The volume may be set too low or muted. You can use Motion Dashboard to increase the
volume or turn mute off. Open Motion Dashboard, then tap Audio and move the slider
to the desired volume.

• The integrated audio components may have been overwritten. If you install a third-party
audio device (such as a USB or Bluetooth device), the integrated audio may stop
working. If this happens, reinstall the audio drivers. After you install these, if you still have
problems recording, contact your system administrator or service provider.
