Safety instructions
y Please read these instructions carefully and completely
before using the system.
y Make these instructions easily accessible to all users at all
times. Always include these instructions when passing the
system on to third parties.
y Do not wear the headphones in situations which require
special attention (e.g. when performing skilled jobs).
y Always keep the system dry and do not expose it to extreme
temperatures (ideally 10-35°C).
y Use the system with care and set it up in a clean, dust-free
environment.
y Varnish or furniture polish may degrade the rubber feet of
the transmitter, which could stain your furniture. You should
therefore place the transmitter on a non-slip pad to avoid
potential staining of furniture.
y This system allows you to set higher volumes than
conventional stethoset systems. This can cause hearing
damage in persons with healthy hearing and especially in
children.
y Please observe the safety instructions for NiMH rechargeable
batteries on the enclosed leaflet.

y having read these instructions, especially the chapter
“Safety instructions”.
