Important Safety Instructions

Control Unit and Charger
General
• READ these instructions.
• KEEP these instructions.
• HEED all warnings and follow all instructions.
Exemption from liability
• beyerdynamic GmbH & Co. KG will not be liable if any damage, injury or accident occurs due to negligent, incorrect or inappropriate
operation of the product.
Location
• The equipment must be set up so that the mains switch, mains plug and all connection 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 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.
Ventilation
• This equipment needs adequate ventilation. Do not cover ventilation grilles. If the heat it generates cannot be dissipated, the equipment
could be damaged or flammable materials in its immediate vicinity could be ignited. Take care to ensure that the air can circulate freely
through the ventilation grilles and keep flammable materials away.
• Do not insert objects into the ventilation grilles or other openings. You could damage the equipment and/or injure yourself.
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.
• 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.
• Do not defeat the safety purpose of the polarised or grounding-type plug. A polarised 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 is provided for your safety.
If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
• Unplug the device during lightning storms or when unused for long periods of time.
• 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.
• If the power cable is connected, avoid contact of the unit with other metallic objects.
• 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.
• When installing the device into a 19" rack, make sure that the mains switch, mains plug and all connection on the rear of the device are
easily accessible.
