Safety instructions
Please read this instruction manual carefully and completely before
using the products.
Make this instruction manual easily accessible to all users at all
times. Always include this instruction manual when passing the
products on to third parties.
Do not use the products in situations which require special atten-
tion (e.g. when performing skilled jobs).
Always keep the products dry and do not expose them to extreme
temperatures.
Use the products with care and set them up in a clean, dust-free
environment.
•Varnish or furniture polish may degrade the 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.
This receiver allows you to set higher volumes than conventional
receivers to which headphones can be connected. This can cause
hearing damage in persons with healthy hearing and especially in
children.
Refer all servicing to qualified service personnel. Servicing is
required if the products have been damaged in any way, liquid has
been spilled, objects have fallen inside, the products have been
exposed to rain or moisture, do not operate properly or have been
dropped.
WARNING: To reduce the risk of fire or electric shock, do not expose
the products to rain or moisture.
Use only the supplied mains unit.
Disconnect the mains connector from the wall socket
to completely disconnect the products from the mains,
during lightning storms or when unused for long periods of time.
Ensure that the mains unit is
always readily operable and easily accessible,
properly plugged into the wall socket,
not covered or exposed to direct sunlight for longer periods of
time in order to prevent heat accumulation,
only operated within the permissible temperature range (see
“Specifications” on page 32),
not operated near heat sources.
