Operational license information
Wireless communication is strictly regulated in most countries, for the sake of public safety (air traffic
commincation, rescue service communication) as well as personal convenience (quality of TV, WiFi
and mobile phone services). For the use of wireless microphones, most countries have a reserved
frequency band. Operation in this frequency band however is in some countries or at some frequen-
cies still subject to governmental approval, for which the user must apply prior to operation. Users of
wireless microphone systems are OBLIGED to make themselves aware of their locally permitted
frequencies and the required registration/approval procedures PRIOR to operation. For EU markets,
the WMU401 is delivered with all frequencies (863.010MHz, 863.420MHz, 864.300MHz,
864.990MHz) inside the license and registration-free ISM band (863-865MHz, TV channel 70). The
unit complies further with EN301489-1/-9 and EN300422-1/-2 and as such adheres to the R&TTE
directive of the European Union and does not need an individual EC type examination of every member
state. Outside of the EU, regulations differ. Contact your local authorities prior to operation.
Health advice
This unit produces and absorbs electromagnetic radiation. The strength of radiation and the sensitiv-
ity for disturbing interference matches the CE and FCC requirements. A corresponding sign is printed
on the backside of the unit. Any change or modification may affect the behavior of the unit concerning
electromagnetic radiation, with the CE requirements eventually not to be met any more. The manufac-
turer takes no responsibility in this case.
Functional advice
This unit is immune to the presence of electromagnetic disturbances – both conducted and radiated
- up to a certain level. Under peak conditions, the unit is classified to show a “class C” performance
criteria and may encounter temporary degradation or loss of function which may need manual help
to recover. In such case, disconnect the AC power from the unit and reconnect it again to recover.
Environmental advice
This unit is built to conform to the ROHS standards and the WEEE directive 2002/96/EC of the
European Parliament and of the Council of the European Union. Under these regulations, the product
shall not be discarded into regular garbage at the end of its life, but shall be returned to authorized
recycling stations.

Description
The WMU401 is a compact combination of 4 wireless high quality UHF microphone links in one single
system. It is designed to make optimal use of a 2MHz bandwith and thus does not require switchable
frequencies, since interference-free operation in such bandwith predetermines the frequency choice.
The frequency choice allows license-free operation in many countries. The WMU401 is available in
different configurations of wireless and beltpack transmitters, which are color-coded for ease of
visual assignment between transmitter and receiver. The multitude of wireless links, the ease of setup
and operation, and the low cost of ownership make this system perfect for any budget-sensitive
muilti-link application.
