Precautions
■ Cleaning
• Clean the cabinet and panel with a dry soft cloth.
• A slightly damp cloth may be used to remove stubborn grime and dirt.
• Never use cleaners such as alcohol or thinner.
• Avoid placing vinyl objects on top of the instrument (vinyl can stick to and discolor
the surface).
You may notice one or more fine diagonal lines on the panel of your QY8. These are
unavoidable in the manufacturing process and are not scratches or defects in the
product.
■ Electrical Interference
• This instrument contains digital circuitry and may cause interference if placed too
close to radio or television receivers. If this occurs, move the instrument further away
from the affected equipment.
■ Data Backup
• The QY8 contains a special long-life battery that retains the contents of its internal
RAM memory even when the power is turned OFF. The backup battery should last
for several years. To ensure reliable operation we recommend that you have the
backup battery replaced by qualified Yamaha service personnel approximately once
every 5 years. DO NOT ATTEMPT TO REPLACE THE BACKUP BATTERY
YOURSELF!
• Internal memory data can be corrupted due to incorrect operation. We recommend
that you use the QY8 Data Out function (see page 61 for details) to transfer
important data to a MIDI data recorder such as the Yamaha MDF2 MIDI Data Filer
for safe long-term storage. Yamaha cannot be held responsible for data loss caused by
battery failure or improper operation of the QY8!
■ Service and Modification
• The QY8 contains no user serviceable parts. Opening it or tampering with it in
anyway can lead to irreparable damage and possibly electric shock. Refer all servicing
to qualified YAMAHA personnel.
YAMAHA is not responsible for damage caused by improper han-
dling or operation.
