Signal transmission


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

Transceiver unit

  • SE 6602) for radio and infrared transmission
  • SE 6422) for infrared transmission

TT switch-on/off

Radio or infrared signal (selectable) from SE

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
