Establishing a radio link

To establish a radio link between the transmitter and receiver, the same frequency must be set in both devices. Before using the device, check whether there are interfering frequencies in your frequency range (Finding an interference-free frequency (frequency test)) and then carry out a soundcheck (Performing a soundcheck).

You have the following options to establish a radio link:

Set the frequency on the transmitter manually (see Setting the frequency on the transmitter) and synchronize it with the receiver (see Synchronizing devices).
Select a frequency already preset on the transmitter and synchronize it with the receiver (see Synchronizing devices). In this case, you can select the frequency bank (see Selecting the frequency bank on the transmitter) and the transmission channel (see Selecting the frequency channel on the transmitter).
Set the same frequency on both devices (see Setting the frequency on the transmitter and Setting the frequency on the receiver). Synchronization is not necessary in this case.

Setting notes

Please note the following when synchronizing a transmitter with a receivers:

Only use transmitters and receivers from the same frequency range (see the type plate on the transmitter and receiver).
Make sure that your chosen frequencies are listed in the frequency table for the particular frequency range (see Frequency tables).
Ensure that the desired frequencies are permitted in your country and apply for an operating license if necessary.
