Disable Bluetooth
NOTE If there is an active Bluetooth connection between the MC55 and another Bluetooth device, the MC55 will not
timeout. However, if the user presses the Power button on the MC55, the MC55 will suspend and upon
receiving data from a remote Bluetooth device, the MC55 will wake from suspend mode. For example,
headset redial or Bluetooth scanner sending data to the MC55.
NOTE On devices with Windows Mobile 6.5.3, turn the Bluetooth radio on or off using the Wireless Manager. Tap the
Status bar and select the Connectivity icon. Tap Wireless Manager.
