9. Do not defeat the safety purpose of the polarized or grounding-
type plug. A polarized plug has two blades with one wider than
the other. A grounding type plug has two blades and a third
grounding prong. The wide blade or the third prong are provided
for your safety. If the provided plug does not fit into your outlet,

10. Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by
the manufacturer, or sold with the apparatus. When a cart is used,
use caution when moving the cart/apparatus combination to
avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused
for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way, such
as power supply cord or plug is damaged, liquid has been spilled
or objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has
been dropped.
Location
• The equipment must be set up so that the mains switch, mains plug
and all connections on the rear of the device are easily accessible.
• If you transport the equipment to another location take care to
ensure that it is adequately secured and can never be damaged by
being dropped or by impacts on the equipment.
Fire hazard
• Never place naked flames (e.g. candles) near the equipment.
Humidity / heat sources
• Never expose the equipment to rain or a high level of humidity. For
this reason do not install it in the immediate vicinity of swimming
pools, showers, damp basement rooms or other areas with unusually
high atmospheric humidity.
• Never place objects containing liquid (e.g. vases or drinking glasses)
on the equipment. Liquids in the equipment could cause a short
circuit.
• Do not install near any heat sources such as radiators, heat registers,
stoves or other apparatus (including amplifiers) that produce heat.
Connection
• The equipment must be connected to a mains socket that has an
earth contact.
• Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the point where
they exit from the apparatus.
• Lay all connection cables so that they do not present a trip hazard.
• Whenever working on the inputs and outputs of the equipment
switch off power.
• Check whether the connection figures comply with the existing
mains supply. Serious damage could occur due to connecting the
system to the wrong power supply. An incorrect mains voltage
could damage the equipment or cause an electric shock.
• Please note that different operating voltages require the use of
different types of power cable and plugs.
Please refer to the following table:
• If the equipment causes a blown fuse or a short circuit, disconnect
it from the mains and have it checked and repaired.
• Do not hold the mains cable with wet hands. There must be no
water or dust on the contact pins. In both cases you could receive
an electric shock.
• The mains cable must be firmly connected. If it is loose there is a fire
hazard.
• Always pull out the mains cable from the mains and/or from the
equipment by the plug – never by the cable. The cable could be
damaged and cause an electric shock or fire.
• Do not use the equipment if the mains plug is damaged.
• If you connect defective or unsuitable accessories, the equipment
could be damaged. Only use connection cables available from or
recommended by beyerdynamic. If you use cables you have made
up yourself, all claim to warranty is null and void.
• In order to disconnect the receiver from AC power, switch it off and
disconnect the power plug from the power socket.
Maintenance
• Only clean the equipment with a slightly damp or dry cloth. Never
use solvents as these damage the surface.
Trou e shooting and servicing
• Do not open the equipment without authorisation. You could
receive an electric shock. There are no user-serviceable parts inside.
• Leave all service work to authorised expert personnel.
2. Disposal
• This symbol on the product, in the instructions or on the
packaging means that your electrical and electronic
equipment should be disposed at the end of its life
separately from your household waste. There are separate
collection systems for recycling in the EU. For more
information, please contact the local authority or your
retailer where you purchased the product.
