rised specialists.
2.4.2 Operation
• Work on the unit may only be carried out by authorised specialists.
2.5 Electrical safety
• Carry out work on the device in accordance with the local safety regulations.
• Observe the safety regulations of the current standards EN 60728-11 and EN 62368-1 or the
national standards.
• Work on the device may only be carried out when the mains is unplugged.
• Replace damaged cables and connectors immediately.
• Connect the unit to a potential equalisation system in accordance with the locally applicable
electrical standards.
• Device does not have a main switch. As soon as the device is plugged in, it is in operation. In
order to turn off the power supply, the mains plug must be removed from the mains socket.
Mains socket must be easily accessible so that the mains plug can be pulled quickly if neces-
sary. Never pull the cable.
• The power supply area of the device as well as all coaxial interfaces with remote power sup-
ply carry dangerous voltages.
• Dangerous live parts must not be touched.

• Do not mount the device on or near flammable materials.
• Never operate the device without a lid/protective cover.
2.6 ESD protection
The device contains components that are sensitive to electrostatic discharges. In case of im-
proper handling, the device may be damaged, e.g. during unpacking, assembly/disassembly,
storage or shipping.
A harmful discharge can happen unnoticed.
Always take the usual protective measures when handling the device.
3 CE-Declaration of Conformity

45 dB. Without a plugged-in module, the attenuation is 0 dB. The configuration of the module is
displayed via the LED:
LED Description
Off No microreceiver plugged in
green Microreceiver plugged in, ICS = 0 dB
orange Microreceiver plugged in, ICS = 6 dB
red Microreceiver plugged in, ICS = 45 dB
1. Insert the VT 21 module into the M10 slot.
