Safety instructions

Intended useThis device is used to convert acoustic signals into electrical signals as well as their wireless transmission. Any other use or use under other operating conditions is considered to be improper and may result in personal injury or property damage. No liability will be assumed for damages resulting from improper use.

Danger for childrenEnsure that plastic bags, packaging, etc. are disposed of properly and are not within reach of babies and young children. Choking hazard! Ensure that children do not detach any small parts from the product. They could swallow the pieces and choke! Never let children unattended use electrical devices.

Danger to life by distractionUsing earphones or headphones may divert your attention from the environment. Ambient noise may not be audible. Do not use the device in road traffic or when operating machinery.

Possible hearing damageWith headset connected, the device can produce volume levels that may cause temporary or permanent hearing impairment. Do not operate the device permanently at a high volume level. Decrease the volume level immediately if you experience ringing in your ears or hearing impairment.

Notes on wireless transmissionThis device utilizes frequencies that are not harmonized within the European Union (EU) and therefore may only be used in certain EU member states. In all European countries, the frequencies used for the transmission of audio signals are strictly regulated. Before you start, make sure the frequencies are allowed in the respective country and check whether the operation must be reported to the appropriate authority.

  • Never set multiple transmitters to the same channel.
  • Make sure that there are no metal objects between the transmitter and receiver.
  • Avoid interference from other radio or in-ear systems.

Incorrect handling of lithium batteries can result in injury

  • In the event of a short circuit, overheating or mechanical damage, lithium batteries can cause severe injuries.
  • When handled correctly and appropriately lithium batteries pose no risk.
  • Store lithium batteries in a cool, dry place, ideally in the original packaging.
  • Store lithium batteries away from heat sources (e.g. radiators or sunlight). Lithium batteries are hermetically sealed. Never attempt to open a lithium battery.
  • If the battery housing is damaged small amounts of the electrolyte may leak out. If this should happen, seal the lithium battery in airtight packaging and wipe up the traces of electrolyte using absorbent paper towels. You must wear protective rubber gloves when doing so. Clean your hands and the affected surface thoroughly with cold water.
  • Never attempt to recharge non-rechargeable lithium batteries. When charging lithium batteries you must use a suitable charging device intended for the purpose.
  • Before disposing of the device remove the lithium batteries. Protect used lithium batteries against potential short circuits, e.g. by covering the poles with adhesive tape.
  • Only use powder extinguishers or other suitable extinguishing agents to extinguish a burning lithium battery.

Possible damage to lithium-ion batteries through incorrect storage

By deep discharge, lithium-ion batteries can be permanently damaged or lose some of their capacity. Before long breaks, charge the batteries to around 50 % of their capacity and then switch off the device. Store the device at room temperature or cooler in an environment as dry as possible. If the batteries are stored for a longer period, recharge them to 50 % every three months.

Fully charge the batteries only shortly before use at room temperature.

Electromagnetic compatibility with other electrical equipment

Using the device near radios or TV sets may cause interference. Then increase the distance between the devices.

    • Turn on the headset with button (3). Press and hold button (3) for three seconds to activate the Bluetooth® function. The LED flashes blue.
    • Turn on the player and activate the Bluetooth® function there. If the device was previously paired with another device, this device must now be turned off or out of range.
    • Have the player search for Bluetooth® devices and select `HD2000NC’ from the device list for connection.
    • After successful connection, the LED lights up constantly blue. A later reconnection of the two devices will be established automatically.
  4. Put on the headphones and adjust the variable headband so that the two ear cups sit directly over your ears.
