WARNING!
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. Follow the advice on
the correct handling of lithium batteries in the present section.
CAUTION!
Possible hearing impairment
The use of earphones at high volume over a longer period of time can cause permanent hearing damage. Adjust the output volume
of your audio device to a medium value and use the earphones no longer than about one hour a day.
NOTICE!

This device has been designed for indoor use only. To prevent damage, never expose the device to any liquid or moisture. Avoid
direct sunlight, heavy dirt, and strong vibrations. Only operate the device within the ambient conditions specied in the chapter
‘Technical specications’ of this user manual. Avoid heavy temperature uctuations and do not switch the device on immediately
after it was exposed to temperature uctuations (for example after transport at low outside temperatures). Dust and dirt inside can
damage the unit. When operated in harmful ambient conditions (dust, smoke, nicotine, fog, etc.), the unit should be maintained by
qualied service personnel at regular intervals to prevent overheating and other malfunction.

NOTICE!
External power supply
The device is powered by an external power supply. Before connecting the external power supply, ensure that the input voltage (AC
outlet) matches the voltage rating of the device and that the AC outlet is protected by a residual current circuit breaker. Failure to do
so could result in damage to the device and possibly the user. Unplug the external power supply before electrical storms occur and
when the device is unused for long periods of time to reduce the risk of electric shock or re.
NOTICE!
Risk of re due to incorrect polarity
Incorrectly inserted batteries may destroy the device or the batteries. Ensure that proper polarity is observed when inserting bat‐
teries.
NOTICE!
Possible damage by leaking batteries
Leaking batteries can cause permanent damage to the device. Take batteries out of the device if it is not going to be used for a
longer period.
NOTICE!
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 envi‐
ronment 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.

The plasticiser contained in the rubber feet of this product may possibly react with the coating of your parquet, linoleum, laminate
or PVC oor and after some time cause permanent dark stains. In case of doubt, do not put the rubber feet directly on the oor, but
use felt-pad oor protectors or a carpet.
NOTICE!
Radio interference
This device emits electromagnetic signals. This can cause interference due to overlapping radio waves. Do not use the device in

4.2 Dealing with lithium batteries
WARNING!
Incorrect handling of lithium batteries can result in injury
In the event of a short circuit, overheating or mechanical damage, lithium bat‐
teries can cause severe injuries.
Follow the advice on the correct handling of lithium batteries in the present sec‐
tion.
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 aected surface thoroughly with cold water.

Never attempt to recharge non-rechargeable lithium batteries. When charging lithium bat‐
teries 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.
