It had only one button that was used to power on and off, channel up, channel down, and mute. The Flash-matic's phototechnology was a significant innovation in television and allowed for wireless signal transfer previously exclusive to radio.〔 == Design and production == Earlier remotes could turn sets on/off and change channels, but were connected to the TV with a cable. The Flash-matic came in response to consumer complaints about the inconvenience of these cables running from the transmitter to the TV monitor. Earlier remotes served as the central control system for transmitting complex signals to the receiving monitor. The Flash-matic instead placed the complexity in the receiver as opposed to the transmitter. It used a directional beam of light to control a television outfitted with four photo cells in the corners of the screen. The light signal would activate one of the four control functions, which turned the picture and sound on or off, and turned the channel tuner dial clockwise and counter-clockwise. The bottom receptors received the signal to mute and power on/off, and the upper cells received signals to channel up/down. In order for the various signals to be received by the monitor, the remote control had to be directed towards one of the four photocells. The system responded to full-spectrum light so could be activated or interfered with by other light sources including indoor light bulbs and the sun. Despite these defects, the Flash-matic was remained in high demand. In September 1955, Zenith released an apology for its inability to meet the high demand of consumers.〔 Chicago Tribune, September 12, 1955, A3. 〕〔 Dawson, Bret Maxwell. TV Repair: New Media "solutions" to Old Media Problems. UMI, 2008, 67. 〕 The Flash-matic was quickly replaced by new control systems. The "Zenith Space Command" remote control went into production in 1956 with aims to improve upon the Flash-matic's design. 〔Benson-Allott 2015, p. 41〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Zenith Flash-matic」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
