SIMULTANEOUS OPERATION OF SEVERAL SYSTEMS
Your neighbour also likes listening with radio
headphones? No problem! With switch µ,
you simply select a different transmission
channel on each transmitter. Then set the
stethoset receivers to the respective frequencies
(with control ¶, as described above). Observe a
minimum distance of 2 m between two transmitters.
Due to the required approval two channels are selectable:
IMPORTANT!
Only use the transmitter with a suitable Sennheiser mains unit. Always disconnect the mains connector
when you wish to change connections or move the device to a different place.
Never open electronic devices! This must only be done by authorised personnel and is all the more valid
for repairs on current-carrying units.
Keep the system away from central heating radiators and electric heaters. Never expose it to direct sunlight.
Use the system in dry rooms only. Transmitter and plug-in mains unit should always remain indoors.
You can use the stethoset receiver outside if the weather is dry.
Use a damp cloth for cleaning the transmitter and the stethoset receiver. Do not use any solvents. For
reasons of hygiene, the ear-cushions can be cleaned with soapy water. We recommend, however, to
simply replace them (inexpensive replacement ear-cushions are available as accessories).
Vanish or furniture polish may degrade the rubber feet of the transmitter. Place the transmitter on a
nonslip pad to avoid potential staining of furniture.
VOLUME UP? - NO!
When people use headphones, they tend to choose a higher volume than with loudspeakers. Listening at
high volume levels for a long time can lead to permanent hearing defects. Please protect your hearing,
Sennheiser headphones also sound exceptionally good at low volumes.
Positions 1 or 3 = channel 1
