Conventional and Rechargeable Batteries
These headphones use a built-in rechargeable Lithium-Ion battery. The rechargeable battery may
only be removed or replaced by an authorized service centre.
Insert the batteries with the correct polarity. Refer to the polarity markings inside the battery
compartment. Do not try to recharge the batteries and do not throw batteries into the fire. Do not
mix battery types (old and new or carbon and alkaline, etc.). Remove the batteries when the
device is not to be used for a long time. Improper use may cause explosions and danger to life.
Respect the environment. Old batteries do not belong in the domestic waste.
They must be handed in to a collection point for waste batteries.
RF Interface
Turn the device off when onboard an aircraft, in a hospital, in an operating theatre or in the
vicinity of medical electronic equipment. The RF signals may interfere with the functionality of
sensitive devices. Place the device at least 20 cm (8 inches) away from pacemakers, as the RF
signals may interfere with the functionality of the pacemaker. The transmitted RF signals can cause
interference with hearing aids. Do not place the device with the wireless adapter turned on near
flammable gases or in a potentially explosive area (e.g. a paint shop), as the transmitted RF
signals may cause explosions or fire.
The range of the radio wave signals depends on environmental conditions. When data is
transmitted via a wireless connection it may also be received by unauthorized parties. The
manufacturer is not liable for any interference caused to RF or TV signals as a result of
unauthorized modifications to this device. Furthermore, the manufacturer does not assume any
liability for replacing any cables or devices that have not been specifically approved by the
manufacturer. The user is solely responsible and liable for troubleshooting any interference
caused by unauthorized modification of this device and for replacing appliances.
