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.
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.

• 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.
