Cleaning the diversity receiver
Using freely selectable receiving frequencies
You can also freely select the receiving frequencies and store these
frequencies in the frequency banks “
U1 ” to “ U6 ”.
̈
Set each diversity receiver to the same frequency bank (“ U1 ” to “ U6 ”).
̈
On one of the receivers, select a channel within this frequency bank and
assign this channel a receiving frequency (see page 25).
̈
Synchronize a transmitter with this receiver (see the instruction
manual of the transmitter).
OR:
̈
Manually set the transmitter to the same frequency bank and channel
that you set on the receiver.
̈
Repeat for the remaining transmitters and receivers as described
above.
Cleaning the diversity receiver
̈
Use a cloth to clean the diversity receiver from time to time.
It might be that the freely selected frequencies are not inter-
modulation-free
If you are using frequencies from the frequency banks “ U1 ” to
“ U6 ”, it might be that the receiving frequencies are not intermod-
ulation-free.
̈
Contact your Sennheiser partner who will be pleased to
calculate intermodulation-free frequencies for you (see
www.sennheiser.com).
CAUTION! Liquids can damage the electronics of the receiver!
Liquids entering the housing of the device can cause a
