– Do not operate the device in wet rooms and protect it from dripping and
splashing water. Make sure that no vases or other liquid-lled objects are
located on or near the device in order to prevent liquid from penetrating
the housing. If water or other debris ends up penetrating the housing,
immediately pull the mains plug. Then send the device to our service

locations, on wobbly tripods or furniture, on under dimensioned brackets
etc. The speaker may tip or fall over and cause injury to persons or be
damaged itself.
– Place the speaker in such a way that it cannot be knocked over inadvertently
and make sure that the cables do not pose a tripping hazard.
– Do not place the speakers near heat sources (e.g. heaters, ovens, other heat
generating equipment such as ampliers etc.).

a danger of suffocation.
– Ensure that children do not remove small parts from the device or take them
off the device (e.g. buttons or plug adapters). They could swallow the parts
and choke.
Leaking battery acid may lead to chemical burns.
– Do not allow battery acid to come into contact with skin, eyes or mucous
membranes. In the event of contact with battery acid, immediately ush
the applicable areas with plenty of clean water and consult a physician if
necessary.

– Only use batteries of the same or equivalent type.
– You must not heat or short circuit batteries and rechargeable batteries or
dispose of them in re.

11
English
– Do not expose batteries and rechargeable batteries to direct sunlight.
Extended listening at high volumes may lead to hearing loss.
– When the volume is set high, always keep a certain distance from the device
and never place your ear directly on the speaker.
– If a speaker is set to full volume, this may produce very high sound pressure.
This may have psychological consequences and also cause physical injury.
Children and pets are particularly at risk. Set your signal source device
volume control to a low setting before turning on the power.
This product contains magnetic material.
– If necessary, consult your physician and ask for effects on implants such as
pacemakers or debrillators.
The isolation pads can produce discoloration on sensitive surfaces.
– On parquet, varnished wood and similar surfaces, you should stick felt gliders
to the rubber feet of the speaker or put blankets or small carpets under it.
This will prevent discoloration of the oor over the long term.

Rechargeable Battery
The integrated Li-Ion rechargeable battery pack will be charged as soon as the
BOOMSTER is supplied with power via the 12 volt connection.
Before rst use, charge the rechargeable battery for approx. 3 hours. In standby,
the charging of the rechargeable battery is indicated by ve plus symbols (+) on
the display panel.
That or the last plus symbols ash and indicate the charge level of the
rechargeable battery. The ashing will stop once the rechargeable battery has
been fully charged. The typical playback time with full charged internal battery
is approx. 16 hours. To protect the rechargeable battery, the BOOMSTER has
deep discharge protection, which switches the device off once the threshold is
reached.
If the charge of the rechargeable battery diminishes or the batteries
are depleted, the message “BATTERY” will fast ash three times every
10 minutes on the display panel. In this case, connect the mains cable.
