Troubleshooting

If a fault occurs, first check the points listed below before taking the set for repair.

If you are unable to remedy a problem by following these hints, consult your dealer or service centre.

WARNING: Under no circumstances should you try to repair the set yourself, as this would invalidate the warranty.

No sound	– Check if the AC/DC adapter is fully inserted into the
	AC outlet and that its DC connector is properly inserted
	into the 12 Volt DC input connector located at the rear
	of the transmitter.
	– Check if the headphone’s on/off switch is in the on
	position.

	source/ headphone to a higher level.

	advanced technologies used in the HC135 headphone.

	sources. Move transmitter or headphone elsewhere.
