Safety instructions
Before using the Bluetooth
®
headphones SBTH 2.1 A1 for the first time, please read
the following instructions carefully and take note of the safety warnings, even if you
are familiar with the use of electronic devices. Store these instructions in a safe
place for future reference. If you sell the device or pass it on, always include these
instructions.
Health risks due to high volume
Take care when using headphones. Listening at high volume
for prolonged periods of time can damage your hearing.
Before putting on the headphones, set the volume to the
lowest level.
Operating environment
The device is not designed for use in environments with a high temperature or
humidity (e.g. bathrooms) or in extremely dusty conditions. Operating temperatures
and operating air humidity: 0°C to 45°C, max. 85% rel. air humidity.
Radio interface
Turn the device off in aircraft, hospitals, operating rooms or in the vicinity of medical
electronic systems. The transmitted radio waves can impair the functionality of
sensitive devices. Keep the device at least 20cm away from any pacemakers, since
the proper functioning of the pacemaker can be impaired by radio waves. The
transmitted radio waves can cause interference in hearing aids. Do not place the
device in the vicinity of flammable gases or in an explosion-hazard environment
(e.g. paint shop) when the radio components are switched on since the transmitted
radio waves can cause an explosion or a fire. The range of the radio waves is
dependent on conditions in the surrounding environment. In case of data traffic via

SilverCrest SBTH 2.1 A1
English - 7
a wireless connection, it is also possible for unauthorised third parties to receive
data. Targa GmbH is not responsible for radio or television interference caused by
unauthorised changes to this device. In addition, Targa assumes no responsibility for
the replacement or exchange of connecting lines and devices not indicated by
Targa GmbH. Only the user himself is responsible for the elimination of interference
caused by such unauthorised changes and for the replacement or exchange of the
devices.
Ensure that
no direct heat sources (e.g. heating) can affect the device;
no direct sunlight or bright artificial light reaches the device;
any contact with splashed and dripping water and corrosive liquids is avoided
and the device is not operated in the vicinity of water. In particular, the device
should never be submerged in liquid (do not place any items filled with liquid,
e.g. vases or drinks, on or near the device);
no fire sources (e.g. burning candles) are placed on or near the device;
the headphones are not thrown into a fire because the integrated battery may
explode;
no foreign objects penetrate the device;
the device is never subjected to extreme temperature fluctuations as this could
result in condensation and electrical short circuits. If the device was subjected to
extreme temperature fluctuations, however, wait (approx. 2 hours) until the
device has reached ambient temperature before use;
the device is never subjected to excessive shocks and vibrations;
connected cables are always laid in such a manner that nobody can step on
them or trip over them. There is a risk of injury;
no objects are placed on a connected cable and cables are not connected over
sharp edges because they could be damaged otherwise.
