Maintenance and care
Maintenance
The Bösendorfer CEUS was purposefully designed so that voicing and tuning can be performed prac-
tically identically to a typical grand piano. The fallboard may be removed, like on a normal grand pi-
ano. No cables are connected to the piano. For careful removal of the keyboard, a data cable on the
interior wall of the piano’s bass side must be removed. It is easily accessible from the front. Piano
technicians can find downloadable details in the Bösendorfer CEUS Piano Technicians’ User Manual.
Care
CEUS requires the same environmental conditions as any other Bösendorfer grand piano.
Please make sure that the air humidity does not fall below 40% and the room temperature and hu-
midity do not fluctuate heavily.
Troubleshooting and repair
Does not turn on / system does not start / display remains dark
Is the power supply connected to an electrical supply? (This mostly affects operation on-
stage…)
Are functioning fuses in place? For 220 V: 6.3 x 32 8 amperes, surge-proof
For 110 V: 6.3 x 32 12 amperes, surge-proof
Is the keyboard cable connected? (Unhinge the fallboard and check the broadband cable in
the bass area of the keybed.)
Caution:
Shut down the system before inserting the keyboard cable!
Is the red power LED in the display lit?
The power LED can be found above the first white piano key (low A) in the bass.
If not… see above.
If yes:
Auto standby is activated. Press the left arrow button.
The display does not switch to show pieces but continues to show the following: System startup
Wait at least one minute.
The system should switch to piece display after two minutes at the latest.
Cause: incompatible USB stick. (Use the Bösendorfer USB stick.)
Connection between the system and the internal hard drive. combo.exe has crashed.
Restart the system. (Turn off the mains switch—wait 30 seconds—turn on again.)
Check the cable connections between your PC’s hard drive and the system: Is the network
cable connected?
Current supply for PC: 12 V
Check your PC’s hard drive:
Do the control LEDs lit? Was the power button (instead of reset) pressed?
Connect the monitor and mouse, etc.
Tip
: Ctrl-Alt-F1 displays the monitor driver.
Playback does not sound like the recording

Hardly noticeable
For psychoacoustic reasons, the perception of volume differs between active playing and
passive listening.
Change listening position.
Different volume perceived for individual keys: may be psychoacoustic; otherwise service or
calibration may be necessary.
