Orbis – Safety Instructions

Connection
• Protect all cables from being walked on or pinched.
• 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 power supply 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 power supply 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 power supply 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 switch off the device 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.
Trouble 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.

• Always position the microphone units on a secure surface. If the microphone unit falls down, you
can hurt yourself or others or damage the microphone unit.
• To align the gooseneck microphone on the microphone unit and to avoid twisting it too far and
causing premature wear, please note that the gooseneck must be bent no further than an angle of
90° maximum.
