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.

	the tuning control button for about 1 second. Repeat if
	necessary until the red tuning indication lights up.

	tuning button for about 1 second.
