Abstract: The extended error correction process of the present invention corrects (106) error of a data message that has been transmitted a plurality of times. The process first receives the data message at least twice, logically combining the first and second messages received to form an error indication word (101). The error indication word is then used to locate the error locations in each message after which some of the errors are complemented (106), depending on the total number of errors found. The message is then decoded (104) and used for transmit power changes, channel reassignment, to release a call (140), etc.

Abstract: The process of the present invention error corrects subaudible data words that have been transmitted over a voice channel. A data word may be transmitted up to three times (515), if an acknowledge is not received by the transmitter. If any of the three possible repeats of the received data word are decodable an acknowledgement (525) is transmitted. If all three repeats of the data word contain uncorrectable errors a bitwise majority vote (519) is performed on the three data words. If the result of majority vote is decodable, an acknowledgement (525) is transmitted to the sender.

Abstract: A portable radiotelephone (200) adjusts its transmit power responsive to the position of a movable antenna (213). The antenna (213) is movable between a retracted (313) and an extended position (314). The portable radiotelephone (200) transmits at low power when the antenna (213) is retracted and at high power when the antenna (213) is extended. Additionally, the portable radiotelephone (200) can notify a remote base station of the change in transmit power at any time during transmission.

Abstract: A portable radiotelephone with a keypad, alphanumeric character display, and hands free function is disclosed. A movable flip element of the housing covers a keypad and other control buttons when in a closed, on-hook, position and activates the illumination of the keypad, enables the display, and enables the hands free function when in an open, off-hook, position. The duration of keypad illumination and display activation are timed to reduce battery drain and the hands free function may be deactivated with a hookswitch flash.
