Below are some common problems and their solutions for your product. If your problem is not 
among those problems mentioned below then please contact your dealer for further assistance.

A) Problems during installation

Problem 1: Audio device doesn’t have a digital or RCA type line output.

What to do: 

The transmitter analog audio interface can also be connected to headphone type 

outputs (3.5 mm or 6.3 mm type outputs) by using a 3.5 mm-to-RCA or 6.3 mm-to-RCA adapter. 
Please contact your dealer for such an adapter. Usually such outputs have a volume control that 
can be used to adjust the audio output level.

What to do: 

Press the very outside edge of the battery lid firmly into the capsule as illustrated in the

applied to the transmitter.

Check the power outlet using another appliance or a voltage tester.

2nd possible cause: 

Faulty AC adapter.

What to do: 

If possible, check the voltage of the supplied AC adapter. Otherwise contact your
