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 feet of the trans-
mitter, 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 conventi-
onal stethoset systems. This can cause hearing damage in
persons with healthy hearing and especially in children.
y Please observe the safety instructions for Lithium-Ion
rechargeable batteries on the enclosed leaflet.
Intended use of the system
Intended use includes:
y having read these instructions, especially the chapter
“Safety instructions”.
y using the system within the operating conditions as descri-
bed in these instructions.
Improper use

in these instructions or under operating conditions which differ
from those described in these instructions.

The IS 410 stethoset receiver system
The IS 410 is a cordless infra-red stethoset receiver system with
which you can adjust the volume of your TV, radio, personal
stereo and other hi-fi equipment to suit your individual needs.
In addition, the system allows you to move around freely
without the constrictions of cables within the room where the
transmitter is placed.
The IS 410 is particularly easy and intuitive to operate. The
stethoset receiver automatically switches on when you pull the
earbows apart. The volume can be adjusted directly on the
receiver. The speech intelligibility can be enhanced at the press
of a button on the transmitter.
The transmitter has an integrated charging compartment for
storing the receiver and simultaneously charging the receiver’s
rechargeable battery. In addition, a spare rechargeable battery
can be charged in the small charging compartment at the side
of the transmitter.
