Notes on wireless transmission
n This 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.
n Make sure that transmitter and receiver are both tuned to the same channel.
n Never set multiple transmitters to the same channel.
n Make sure that there are no metal objects between the transmitter and receiver.
n Avoid interference from other radio systems, television or radio sets.

Inserting batteries into the
transmitter
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:
n If 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.
n If 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.
Unscrew the lower housing part of the hand-held microphone and open the cover of the bat‐
tery compartment (20) by lifting the clip. Insert the batteries. Pay attention to the correct align‐
ment of the poles. Close the battery compartment and refit the lower housing part by tight‐
ening the screw. Then switch on the transmitter.

Troubleshooting

Symptom Remedy
No sound 1. Check the operating voltage supply of transmitter and receiver.
Troubleshooting
In the following we list a few common problems that may occur during operation. We give you
some suggestions for easy troubleshooting:
2. Make sure that transmitter and receiver operate within the same frequency
range. The respective frequency range is indicated on the units.
3. Are both transmitter and receiver set to the same channel?
4. Check the connection between the receiver and the connected audio device
(amplifier, mixer). Is the connected audio device turned on and is the output
level of the receiver well adjusted for the audio input device?
5. Try to improve the transmission by moving the transmitter closer to the
receiver. Maybe the ‘SQUELCH’ controller is set too high.

Troubleshooting
Symptom Remedy
6. See if any metal parts near the transmitter or receiver interfere with the trans‐
mission.
Transmission is disrupted 1. Change the orientation of the antennas.
2. If you use more than one wireless system at the same time, control the fre‐
quencies and channels used. The systems should work within separate fre‐
quency ranges.
3. Also televisions, radios, or mobile phones can cause interference.
Sound is distorted Change the setting of the ‘VOLUME’ controller on the receiver.
