Abstract
In a radiotelephone (200) having a moveable antenna (213), an apparatus and method generates a control signal (511 or 412) responsive to the movement of the antenna (213). The control signal (511 and/or 412) comprise a hookswitch control signal (511) and/or a power on/off control signal (412). Operating modes of the radiotelephone (200) may be enabled or disabled responsive to the hookswitch control signal (511). The hookswitch control signal (511) or on/off control signal (412) may also be produced by activation of keys on the radiotelephone's keypad (205). The apparatus and method provides convenient user operation, protection from accidental activation of exposed control keys and reduced cost, weight and thickness for the communication device.
