2 Safety instructions
This device is intended to be used for electronic sound generation using a piano key‐
board. Use the device only as described in this user manual. Any other use or use
under other operating conditions is considered to be improper and may result in per‐
sonal injury or property damage. No liability will be assumed for damages resulting
from improper use.
This device may be used only by persons with sucient physical, sensorial, and intel‐
lectual abilities and having corresponding knowledge and experience. Other persons
may use this device only if they are supervised or instructed by a person who is
responsible for their safety.
Safety
DANGER!
Risk of injury and choking hazard for children!
Children can suocate on packaging material and small parts. Children can injure themselves when handling the device. Never
allow children to play with the packaging material and the device. Always store packaging material out of the reach of babies and
small children. Always dispose of packaging material properly when it is not in use. Never allow children to use the device without
supervision. Keep small parts away from children and make sure that the device does not shed any small parts (such knobs) that
children could play with.
WARNING!
Possible hearing damage due to high volumes on speakers or headphones!
With speakers or headphones connected, the device can produce volume levels that may cause temporary or permanent hearing
impairment. Over an extended period of time, even levels that seem to be uncritical can cause hearing damage. 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 impairment.
NOTICE!
Damage to the device if operated in unsuitable ambient conditions!
The device can be damaged if it is operated in unsuitable ambient conditions. Only operate the device indoors within the
ambient conditions specied in the “Technical specications” chapter of this user manual. Avoid operating it in environments
with direct sunlight, heavy dirt and strong vibrations. Avoid operating it in environments with strong temperature uctuations. If
temperature uctuations cannot be avoided (for example after transport in low outside temperatures), do not switch on the
device immediately. Never subject the device to liquids or moisture. Never move the device to another location while it is in oper‐
ation. In environments with increased dirt levels (for example due to dust, smoke, nicotine or mist): Have the device cleaned by
qualied specialists at regular intervals to prevent damage due to overheating and other malfunctions.
NOTICE!
Damage to the external power supply due to high voltages!
The device is powered by an external power supply. The external power supply can be damaged if it is operated with the incor‐
rect voltage or if high voltage peaks occur. In the worst case, excess voltages can also cause a risk of injury and res. Make sure
that the voltage specication on the external power supply matches the local power grid before plugging in the power supply.
Only operate the external power supply from professionally installed mains sockets that are protected by a residual current circuit
breaker (FI). As a precaution, disconnect the power supply from the power grid when storms are approaching or it the device will
not be used for a longer period.
NOTICE!
Possible staining due to plasticiser in rubber feet!
The plasticiser contained in the rubber feet of this product may react with the coating of the oor and cause permanent dark
stains after some time. If necessary, use a suitable mat or felt slide to prevent direct contact between the device’s rubber feet and
the oor.

Digital Piano

Piano key Meaning
[F4] EQUAL
The equal tempered tuning divides the octave
into 12 equal semitone steps. This tuning has
become standard over time because playing all
keys is equally possible.
[G4] JUST MAJOR
A tuning process in which the intervals are
tuned without beat. This creates chords with
great sonority. For physical reasons, this only
works for the major key specied here.
Related chords have low beats, distant chords
(such as F sharp major in a pure C tuning) usu‐
ally sound very out of tune.
[A4] JUST MINOR
A tuning process in which the intervals are
tuned without beat. This creates chords with
great sonority. For physical reasons, this only
works for the minor key specied here.
Related chords have low beats, distant chords
(such as F sharp minor in a pure C tuning) usu‐
ally sound very out of tune.
Many of the functions can be easily controlled from a mobile device using
suitable apps (e.g. PianoToolBox), which can be downloaded from the App
Store® or Google Play.
7.9 Selecting sounds
The digital piano has a total of 25 sounds that can be called up using the [PIANO] /
[EP] / [KEYBOARD] / [SYNTH] / [OTHER] buttons (see Ä Chapter 8 ‘Sound list’
on page 30).
