To establish a radio link between the transmitter and receiver, the same
frequency must be set in both devices.
You can do this in a number of different ways:
1.
Use the Easy Setup function to perform an automatic frequency setup (see “Easy Setup menu item”).
2. Set a frequency in the receiver manually (see “Frequency Preset menu
item”) and synchronize it with the transmitter (see “Synchronizing devices”).
3. Set the frequency on the receiver and the transmitter manually
(EK IEM G4: “Frequency Preset menu item”, SR IEM G4: “Frequency
Preset menu item”).
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.
