follows:

y Press the TUNE button for 5 seconds.

y Turn the headphones off.

y If the acoustic signals are turned on, the headphones produce a

y Check if all jack plugs are connected correctly.

y Make sure that the batteries are charged.

that the volume of the headphnes and sound source is sufficient.

y Move closer to the transmitter.

y Choose a different channel on the transmitter.

y Press the TUNE button again.

Remove the rechargeable batteries from the headphones and –

at the same time – interrupt the power supply of the transmitter

for at least 30 seconds.
