cleansing agents.
Recommendations and tips
CAUTION! Liquids can damage the electronics of the transmitter!
Liquids entering the housing of the transmitter can cause a short-circuit and damage the
electronics.
̈ Keep all liquids away from the transmitter.
... for optimum reception
• Transmission range depends to a large extent on location and can vary from about 10 m
to about 150 m. There should be a “free line of sight” between transmitting and receiving
antennas.
• To avoid overloading the receiver, observe a minimum distance of 5 m between
transmitting and receiving antennas.
... for multi-channel operation
• Each of the frequency banks “1” to “20” accommodates factory-preset receiving
frequencies which are intermodulation-free. For possible frequency combinations,
please refer to the supplied frequency information sheet.
• The channels in the frequency banks “U1” to “U6” can be assigned freely selectable
frequencies (see page 34).
• When using several transmitters simultaneously, interference can be avoided by
maintaining a minimum distance of 20 cm between two transmitters.
• Use accessories recommended by Sennheiser for multi-channel applications (see
page 36).
