CAUTION
Always follow the basic precautions listed below to
avoid the possibility of physical injury to you or others.
These precautions include, but are not limited to, the
following:
Power supply/Power cord
• When removing the electric plug from the product or an
outlet, always hold the plug itself and not the cord. Pulling by
the cord can damage it.
Location and connection
• Do not place the product in an unstable position or a location
with excessive vibration, where it might accidentally fall over
and cause injury.
• Keep the device out of reach of children. This product is not
suitable for use in locations where children are likely to be
present.
• Do not block the vents. This product has ventilation holes at
the front/rear to prevent the internal temperature from
becoming too high. In particular, do not place the product on
its side or upside down. Inadequate ventilation can result in
overheating, possibly causing damage to the product(s), or
even fire.
• When attempting to dissipate heat on the product, when
installing it:
- Do not cover it with any cloth.
- Do not install it on a carpet or rug.
- Make sure the top surface faces up; do not install on its
sides or upside down.
- Do not use the product in a confined, poorly-ventilated
location.
Inadequate ventilation can result in overheating, possibly
causing damage to the product(s), or even fire.
• If the product is mounted in an EIA standard rack, carefully
read the section “Precautions for rackmounting” on page 9.
Inadequate ventilation can result in overheating, possibly
causing damage to the product(s), malfunction, or even fire.
If this product is to be used in a small space other than an
EIA-standard rack, make sure that there is adequate space
around the product: at least 40 cm above, 10 cm at the sides
and 15 cm behind.
• Do not place the product in a location where it may come into
contact with corrosive gases or salt air. Doing so may result in
malfunction.
• Before moving the product, remove all connected cables.
• Use only speaker cables for connecting speakers to the
speaker jacks. Use of other types of cables may result in fire.
Maintenance
• Inspect the cooling fan air filter and clean it periodically (see
page 16). Dust and dirt can seriously degrade the
effectiveness of the cooling fan and result in malfunction or
fire.
• Remove the power plug from the AC outlet when cleaning the
product.
Handling caution
• Do not insert your fingers or hands in any gaps or openings
on the product (vents, panel, etc.).
• Do not rest your weight on the product or place heavy objects
on it.
Internal battery for clock display
• Do not replace the internal battery by yourself. Doing so may
cause an explosion and/or damage to the product(s).
When the internal battery needs to be replaced, “Low
Battery” or “No Battery” will appear on the display. In this
case, contact your Yamaha dealer and have qualified
Yamaha service personnel replace the internal battery.
