ABSTRACT:
A technique for activating a transmit mode of a communication device (100) is provided encompassing the steps of generating a light signal on an outer surface of the communication device; inhibiting the light signal; and activating the transmit mode of the communication device in response to the light signal being inhibited. A communication device (100) operating in accordance with this technique includes a light transmitting device (108); and a sensor (110) for sensing light generated by the light transmitting device, the sensor disabling a transmit mode when light is detected and enabling a transmit mode when light is inhibited.
