    Signal transmission


    Radio or infrared transmission (selectable)
    with 360° range to SE

    Transceiver unit

    • SE 6602) for radio and infrared transmission
    • SE 642 2) for infrared transmission
    • SE 6613) for radio and infrared transmission

    TT switch-on/off

    Radio or infrared signal (selectable) from SE

    * Please select when ordering

    1) Reduced operating time if there is much surrounding radio traffic, or short but frequent probing intervals

    2) SE shared by TS 460 and TT 460, see page 28

    3) With EnDat interface

    4) Reduced operating time if there is high surrounding radio traffic or if probing intervals are short and frequent
