Abstract
A radiotelephone wrist device includes a case having a transceiver and a strap attached to the case for fastening the device to a user's wrist. The strap has a top layer and a bottom layer in which the top layer is releasable from the bottom layer of the strap. A microphone is located on the strap and electrically connected to the transceiver. A speaker is located at an end of the top layer of the strap and electrically connected to the transceiver. A cradle for receiving the speaker is formed in the case. A sensor located beneath the cradle detects when the speaker is removed from the cradle.
