A communication device (10) including control circuitry with transceiver capabilities, input keys coupled to the circuitry for entering information, a display (12) coupled to the circuitry for visual presentation of information, a chassis (16) for securely holding the circuitry and the display (12), a sound generation unit (30, 70, 90, 100) coupled to the circuitry for providing audio presentation of information, and a retaining unit secured to the chassis (16) for releasable retaining the sound generation unit (30, 70, 90, 100) in the inactive position, wherein the retaining unit is operated by a button (34), such that pressing the button (34) causes the retaining unit to release the sound generation unit (30, 70, 90, 100) thereby allowing the sound generation unit (30, 70, 90, 100) to move from an inactive position to an active position. |
