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 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.
Synchronizing devices Synchronizing devices You can synchronize ew IEM G4 series transmitters and receivers via the transmitter’s and receiver’s infrared interfaces. The Easy Setup Sync function makes it possible to transfer unused frequency presets from your EK IEM G4 receiver to multiple transmitters via the infrared interface after you have performed a frequency preset scan with this receiver. The next unused channel in the receiver’s current frequency bank is transferred to your transmitter.
Synchronizing devices ▷ Hold the infra-red interface of the receiver in front of the infra-red interface of the first transmitter. The next unused frequency preset is transferred from the receiver to the transmitter. Once the transfer is complete, the numbers of the transferred frequency bank and the transferred channel appear in the display panel of the transmitter. ▷ Press the jog dial on the transmitter to save the synchronized frequency.
Synchronizing devices Sync function (SR IEM G4 -> EK IEM G4) You can adjust the Parameters to be transferred to the receivers here: “Advanced > Sync Settings menu item”. ▷ Switch the transmitter and the receiver on. ▷ Press the SYNC button on the transmitter. Sync appears in the transmitter’s display and the blue LED turns blue.
Synchronizing devices ▷ Hold the infra-red interface of the receiver in front of the infra-red interface of the transmitter. ► The parameters are transferred to the receiver. The blue LED blinks during transmission. When the transfer is complete, a tick appears in the transmitter’s display as a confirmation. Then the transmitter will return to the standard display. To cancel synchronization: ▷ Press the ESC button on the transmitter. An X appears in the display.
