TERY YOURSELF!
• Internal memory data can be corrupted due to
incorrect operation. We recommend that you
use the QY20 MIDI bulk dump utility (see page
163 for details) to transfer important data to a
MIDI data recorder such as the Yamaha MDF2
for safe long-term storage. Yamaha cannot be
held responsible for data loss caused by battery
failure or improper operation of the QY20!

Opening it or tampering with it in anyway can
