Turning the Bluetooth Radio Mode On and Off
Turn off the Bluetooth radio to save power or if entering an area with radio restrictions (e.g., an airplane). When the
radio is off, other Bluetooth devices cannot see or connect to the MC75A. Turn on the Bluetooth radio to exchange
information with other Bluetooth devices (within range). Communicate only with Bluetooth radios in close proximity.
Enabling Bluetooth
To enable Bluetooth:
NOTE If there is an active Bluetooth connection between the MC75A and another Bluetooth device, the MC75A will
not timeout. However, if the user presses the Power button on the MC75A, the MC75A will suspend (except
when on a call) and upon receiving data from a remote Bluetooth device, the MC75A will wake from suspend
mode. For example, headset redial or Bluetooth scanner sending data to the MC75A.
NOTE If there is an active Bluetooth connection between the MC75A and another Bluetooth device and there is no
