ADVANTAGES Ǡ With cordless sound transmission, you are independent of cables. Only you can hear the sound, and you can decide the volume yourself without disturbing others! Ǡ According to present scientific knowledge, sound transmission by infrared light poses no risk to health whatsoever. Ǡ The new carrier frequencies of 2.3 and 2.8 MHz ensure highest reliability, as this transmission range is not subject to interference from fluorescent tubes or digital controls. Ǡ Mains connection via plug-in mains unit. The transmitter thus remains small and unobtrusive. If you take your system to a country with a different mains voltage, all you need to do is purchase the suitable plugin mains unit. SENNHEISER TECHNOLOGY AND SENNHEISER SERVICE ARE FUTURE-ORIENTED Even after many years, you will still have unlimited pleasure from your infra-red sound transmission system. You can buy replacements for parts subject to wear and tear, such as ear-cushions and accupacks, for many years to come. And in the unlikely event that any repairs should be necessary, Sennheiser Service Departments worldwide give moderately priced, fast and competent repairs. ENVIRONMENT AND HEALTH Devices powered by rechargeable batteries are environmentally friendly. This energy source can be recharged many times. Conventional batteries, on the other hand, must be disposed of as special waste after they have been used just once. Sennheiser uses environmentally friendly NiMh rechargeable accupacks which contain no heavy metals. If an accupack should be defective, it is then recycled - the dealer who sold it to you will take it back and will also supply you with a new, original Sennheiser accupack. (Recycling methods may differ country to country). 14 THIS BOX CONTAINS ... ... several individual products.
