Instrument and Bench Maintenance

As with an acoustic piano, pedals may become tarnished over years of use. When this occurs, polish the pedal with a
compound designed for piano pedals. Before using the compound, make sure to read the instructions for proper usage.
Unlike an acoustic piano, this instrument does not need to be tuned by an expert (although the pitch can be user-adjusted
to match other instruments). This is because the pitch of digital instruments is always maintained perfectly.
You can load this instrument onto a truck, either fully
assembled or disassembled. When doing so, do not lean
the instrument (especially the keyboard unit) against a
wall, and make sure to lay it horizontally in the truck. When
transporting by truck, do not subject the instrument to
excessive vibration or shock. If you transport the
instrument fully assembled, make sure to check all the
screws then tighten them as necessary.

This is the standard piano touch response.
