The invention relates to a recombiner system for catalytically recombining hydrogen that is produced in energy accumulators or energy converters. The apparatus greatly reduces or eliminates the audio noise induced in hearing aids by the PWDs and allows operation of a hearing aid during PWD operation. The content sources can be DVD, CD, CD-ROM, hard disk, RAM, Flash memory or remote sources accessible over a network, such as the Internet. In effect, hot spots degrading screen quality and screen brightness distribution non-uniformity can be prevented. The internal slider is biased towards said closed position.
