Saving data
• When changing the battery for the clock, please contact the
Yamaha service personnel. This product has a built-in battery
for the clock, so even when the power supply is interrupted, it
maintains the time data of the internal clock. When the clock
battery wears out the time data is lost, resulting in time-
related data, such as for scenes, saved in the product, to be
lost. The expected life of the clock battery is 5 years, but may
vary with the usage environment.
• To protect against data loss through media damage, we
recommend that you save your important data onto two USB
storage devices/external media.
