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 con-
sidered 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 electri-
cal devices.
Danger to life by distraction
Using earphones or headphones may divert your attention from the en-
vironment. Ambient noise may not be audible. Do not use the device in
road trac 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 impair-
ment.
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 regu-
lated. Before you start, make sure the frequencies are allowed in the respective coun-
try and check whether the operation must be reported to the appropriate authority.

• Make sure that transmitter and receiver are both tuned to the same channel.
• 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 rub-
ber gloves when doing so. Clean your hands and the aected surface thoroughly
with cold water.
• Never attempt to recharge non-rechargeable lithium batteries. When charging lit-
hium 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 extingu-
ish 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 o the device. Store the device at room temperature or cooler in an environ-
ment 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.
Where to use the product
Never use the product
• in direct sunlight
• in conditions of extreme temperature or humidity
• in extremely dusty or dirty areas
• at locations where the unit can become wet
• near magnetic elds
General handling
• To prevent damage, never use force when operating the switches and controls.
• Never immerse the appliance in water. Just wipe it with a clean dry cloth. Do not
use liquid cleaners such as benzene, thinners or ammable cleaning agents.
Keep foreign substances from the unit!
Keep the device away from containers with liquids. Should any liquid get into the
unit, this could lead to its destruction or re. Be sure not to let any metal objects
into the unit.

Using the device
1. To charge the built-in battery, connect the micro USB port (8) to a powered-on
computer or another USB charging source using the supplied USB cable. During
charging, the LED lights red. After the end of the max. 3-hour charging process,
the LED turns o.
2. 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.
3. For the initial wireless connection to a player via Bluetooth® (A2DP prole), the
two devices must rst be paired as follows:
• Turn on the headset with button (3). Press and hold button (3) for three sec-
onds to activate the Bluetooth® function. The LED ashes 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 o 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 recon-
nection 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.
5. 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 briey
pressing the (3) key. Hold the button (3) for about 1.5 seconds to reject the call.
You can end a call by briey pressing the button (3).

on the player using the button (3). Briey press one of the / buttons
(2) / (4) to decrease or increase the volume. Keep these buttons pressed to skip
to the previous or next le.
7. The active noise cancelling function can be turned on or o, regardless of the
transmission mode, by holding down the (1) key. When activated, the LED lights
green.
8. If the battery voltage drops below 3.3V, two warning tones sound every 60
seconds. If the battery voltage drops below 3.1V, a warning tone sounds. If it
drops below 3V, the device switches o automatically and must be charged.
