Safety instructions
Intended use
This 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 children
Ensure 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 distraction
Using 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 damage
With 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 transmission
This 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. For more information, please visit:

- 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.

- For tethered data transfer, connect the player to socket (6) on the device using the supplied mini jack cable. Using this socket disables the wireless transmission.
- For the initial wireless connection to a player via Bluetooth® (A2DP profile), the two devices must first be paired as follows:
- 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.
- Put on the headphones and adjust the variable headband so that the two ear cups sit directly over your ears.
- If the device is connected to a mobile phone, you can make calls as usual. To call the last number again, press the (3) key twice in rapid succession. You can accept an incoming call by briefly pressing the (3) key. Hold the button (3) for about 1.5 seconds to reject the call. You can end a call by briefly pressing the button (3).
- On wireless connection, you can start or pause playback of an audio file selected on the player using the button (3). Briefly press one of the buttons (2) / (4) to decrease or increase the volume. Keep these buttons pressed to skip to the previous or next file.
