Abstract: A communication device and method are presented. The device is in a network of devices of different groups. The device contains a push-to-talk (PTT) button, a channel selector, and a keyboard containing hard or soft keys. The channel selector selects an initial frequency at which to receive and transmit, dependent on the group to which the device belongs. The device transmits when the PTT button is pressed. If a multiple PTT function is activated by software in the device, at least some of the keys are used to select a new transmission frequency. The device receives at the initial frequency independent of the transmission frequency. The multiple PTT function can be activated by a dedicated soft or hard key or a key on the keyboard that serves multiple functions. The frequency selection provided by the keys is dependent on the channel and the device group.
