[. . . ] The AC 3 antenna combiner incorporates DC distribution to enable simultaneous powering of up to four transmitters via its BNC sockets. These transmitters do not require their individual power supply (see also page 11). 12 Using the transmitter Using the transmitter To establish a transmission link, proceed as follows: 1. Switch the receiver on (see the instruction manual of the receiver). It is vital to observe the notes on frequency selection on page 21. If you cannot establish a transmission link between transmitter and receiver: Make sure that transmitter and receiver are set to the same frequency bank and to the same channel. If necessary, read the chapter "If a problem occurs . . . " on page 23. Switching the transmitter on/off To switch the transmitter on (online operation): Press the STANDBY button ¶.
