Establishing a radio link

Establishing a radio link

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 set up

(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 de vices”).

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 receiv ers:

▷ ▷ ▷

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 ta-

ble 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.
