• BOOMSTER GO
CAUTION
Extended listening
at high volumes may
lead to hearing loss.
To avoid damage to health,
avoid extended listening at
high volumes.
–When the volume is
set high, always keep a
certain distance from the
device and never place
your ears directly on the
speaker.
–If a speaker is set to full
volume, this may produce
very high sound pressure.
This may have psycholog-
ical 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.
CAUTION
This product contains
magnetic material.
–If necessary, consult
your physician and ask
for effects on implants
such as pacemakers or
defibrillators.
NOTICE
The BOOMSTER GO is
watertight in depths of up
to one meter.
–Normal rain and a few
splashes from showering
won’t cause any damage,
but you should avoid
spraying it directly with a
hose.
–If the BOOMSTER GO
falls into a paddling pool,
fish pond or other flat
water body, nothing will
happen if you recover it
right away. However, the
device is not suitable for
prolonged diving!
–You should generally
avoid contact with salt
water.

10 • BOOMSTER GO
NOTICE
Gross misuse and incor-
rect care are the main
reasons for damage
to high-performance
rechargeable batteries.
–Avoid deep discharge of
under 10 % for optimal
rechargeable battery
power.
–Recharge your recharge-
able battery frequently.
–Store your rechargeable
battery in a cool but
frost-free area, ideally at
15 °C. Higher tempera-
tures result in a higher
rate of self-discharge
and shorten the intervals
between charges.
–Do not expose the
rechargeable battery to
direct sunlight or other
sources of heat.
This applies in particular
when charging the
rechargeable battery.
–A deep discharge
damages the recharge-
able battery cells. The
most frequent cause
of deep discharge is
prolonged storage or
failure to use a partially
discharged rechargeable
battery. Only store the
rechargeable battery
once it is fully charged.

• BOOMSTER GO
Old devices must not
be disposed of with
household waste!
If the BOOMSTER GO is no
longer operational, every
consumer is required by law
to dispose of used devices
separately from household
waste, e.g. at a collection
point run by the communal
authority/borough. This
ensures that old devices are
recycled in a professional
manner and also rules out
negative consequences for
the environment.
For this reason, electrical
equipment is marked with
the adjacent symbol.
Used batteries
must not be
disposed of with house-
hold waste!
Every consumer is required
by law to bring all batteries
and rechargeable batteries,
regardless whether they
contain harmful substances
or not, to a collection point
run by the communal
authority/borough or to a
retailer, so that they can be
disposed of in an environ-
mentally friendly manner.
Please only turn in
batteries
and rechargeable batteries
which are empty!

• Of course, you can
also operate the
BOOMSTER GO with a
charger, a PC or a USB
battery pack via the USB
cable. As soon as the
rechargeable battery
is fully charged, the
auto-function will deacti-
vate the charging current
– playback is not inter-
rupted.
Charging the battery
CAUTION
If the device is wet, a
short circuit can occur
during the charging
process.
–Let the device dry
completely before
charging.
The integrated Li-Ion
rechargeable battery is
charged as soon as the
BOOMSTER GO is supplied
with power from the USB
micro port (7).
Three white LEDs on the
rechargeable battery
indicator (4) signalise the
charging process:
100% all 3 LEDs are
illuminated
66-99% 2 LEDs are illu-
minated, one is
flashing
33-65% one LED is
illuminated, 2
are flashing
<32% Sequential light
with all three
LEDs
Room temperature is ideal
for charging the recharge-
able battery. In an exces-
sively cold or hot environ-
ment, the rechargeable
battery doesn’t reach its full
capacity during charging.

16 • BOOMSTER GO
Charge level
You can display the battery
charge level by tapping the
button (5):
66-100% all 3 LEDs are
illuminated
33-65% 2 LEDs are
illuminated
11-32% 1 LED is illumi-
nated
6-10% Warning tone,
1 LED blinks
slowly (1/
second)
<6% Warning tone,
1 LED blinks
quickly (2/
second)
With some smartphones,
the charge level is also
shown on the display.
If the rechargeable
battery charge dimin-
ishes, the BOOMSTER GO
will emit short warning
tones and the left LED
of the rechargeable
battery indicator will
blink. Depending on the
volume, operation will still
be possible for up to 60
minutes.
In this case, connect a USB
charger shortly.
• To protect the recharge-
able battery, the
BOOMSTER GO has
deep discharge protec-
tion, which switches
the device off once the
threshold is reached.
– In this case, the
BOOMSTER GO can not
be switched on again.
