ユーザーズマニュアル目次Telex Model BTR-80N Base Station1Each BTR-80N base station can be used with one to four TR-80N or TR-82N beltpacks. The BTR-80N transmits within the 482 to 608 MHz range (TV Channels 16-36). It receives in the 614 to 722 MHz range (TV Channels 38-55). The BTR-80N transmitters operate within an 18 MHz wide section of the transmit frequency range. The receiver also operates with a single front-end that is 18MHz wide and then block down-converts the received frequencies to four IF strips.1The transmitters have three selectable conducted output power levels; Off, 10mW, 50mW, 100mW and 249mW. This user selectable power level allows intermodulation reduction plus the lower of transmit power to just meet the communication link’s need.1Operating frequencies can be selected from pre-set groups or the user can select special operating frequencies within the 18 MHz wide allotments.1サイズ： 193KBページ数： 5Language: Englishマニュアルを開く
