NOTICE!
External power supply
The device is powered by an external power supply. Before connecting the
external power supply, ensure that the input voltage (AC outlet) matches the
voltage rating of the device and that the AC outlet is protected by a residual cur‐
rent circuit breaker. Failure to do so could result in damage to the device and pos‐
sibly the user.
Unplug the external power supply before electrical storms occur and when the
device is unused for long periods of time to reduce the risk of electric shock or
fire.
NOTICE!
Risk of fire due to incorrect polarity
Incorrectly inserted batteries may destroy the device or the batteries.

nThis devices utilizes frequencies that are not harmonized within the European Union (EU)
and therefore may only be used in certain EU member states. In all European countries, the
frequencies used for the transmission of audio signals are strictly regulated. Before you
start, make sure the frequencies are allowed in the respective country and check whether
the operation must be reported to the appropriate authority.
nMake sure that transmitter and receiver are both tuned to the same channel.
nNever set multiple transmitters to the same channel.
nMake sure that there are no metal objects between the transmitter and receiver.

Connect one of the audio outputs of the receiver to your mixer or amplifier. Make sure that
only one of the two outputs of the receiver is used at the same time. Otherwise, interferences
can by caused.
First adjust the volume control (6) as follows:
nIf you use a microphone input of your mixer, turn the knob to about 1 o'clock. The audio
level at the output sockets will be about 77 mV.
nIf you use a line input of your mixer, turn the knob clockwise to the right stop. The audio
level at the output sockets will be about 770 mV.
In order to achieve optimal sound quality, a fine adjustment may be required.
