product.
왘Always include this instruction manual when passing the product on to third
parties.
왘This instruction manual is also available on the Internet at
www.sennheiser-aviation.com or www.sennheiser.com.
Preventing health problems and accidents
왘Always maintain a distance of at least 3.94“ (10 cm) between the ear cups and
the cardiac pacemaker or implanted defibrillator since the product generates
permanent magnetic fields.
왘Keep product, accessory and packaging parts out of reach of children who
could swallow smaller pieces.
왘Switch the product off after use to conserve battery power. Remove the
rechargeable batteries if the product will not be used for extended periods of
