Make this instruction manual easily accessible to all users at all times. Always include this instruction manual when passing the product on to third parties. This instruction manual is also available on the Internet at www.sennheiser.com. Preventing health problems Before using the product, set the volume to a low level. To protect your hearing, avoid listening at high volume levels for long periods of time. Do not use the product in situations which require special attention (e.g. in traffic or when performing skilled jobs). The product generates stronger permanent magnetic fields that could cause interference with cardiac pacemakers and implanted defibrillators (ICDs). Always maintain a distance of at least 3.94” (10 cm) between the ear piece housing and the cardiac pacemaker or implanted defibrillator. Preventing damage to the product Always keep the product dry and do not expose it to extreme temper- atures (normal operating temperatures: 5°C/41°F to 40°C/104°F). Use the product with care and store it in a clean, dust-free environ- ment. Varnish or furniture polish may degrade the feet of the trans- mitter, which could stain your furniture. You should therefore place the transmitter on a non-slip pad to avoid potential staining of furniture. Switch the headphones off after use to conserve battery power. Remove the batteries if the headphones will not be used for extended periods of time. Preventing damage to the power supply unit To reduce the risk of fire or electric shock, do not expose the product to rain or moisture. Unplug the mains unit from the wall socket to completely disconnect the product from the mains, during lightning storms or when unused for long periods of time. Only operate the mains unit from the type of power source specified in the chapter “Specifications”. To prevent heat accumulation, always ensure that the mains unit is in a safe operating condition and easily accessible, properly plugged into the wall socket and not covered or exposed to direct sunlight for longer periods of time. Only use the power supply units, charging cables and accessories recommended by Sennheiser.
