- When the batteries run out, or if the product is not to be
used for a long time, remove the batteries from the
product.
- Do not attempt to recharge batteries that are not
designed to be charged.
• If the batteries do leak, avoid contact with the leaked fluid.
If the battery fluid should come in contact with your eyes,
mouth, or skin, wash immediately with water and consult a
doctor. Battery fluid is corrosive and may possibly cause
loss of sight or chemical burns.
• When using rechargeable batteries, follow the instructions
that came with the batteries. Use only the specified charger
device and within the specified charging temperature
range when charging.
Charging with an unspecified charger or at a temperature
outside the range may cause leakage, overheating,
explosion, or malfunction.
CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or
damage to the product or other property. These precautions include, but are not limited to, the following:
Location
• Do not place the product in an unstable position or a
location with excessive vibration, where it might
accidentally fall over and cause injury.
Connections
• Before connecting the product to other electronic
components, turn off the power for all components. Before
turning the power on or off for all components, set all
volume levels to minimum.
• Be sure to set the volumes of all components at their
minimum levels and gradually raise the volume controls
while playing the product to set the desired listening level.
Yamaha cannot be held responsible for damage caused by improper use or modifications to the product, or data that is lost or
destroyed.
Always turn the power off when the product is not in use.
Even when the [P] (Standby/On) switch is in standby status (display is off ), electricity is still flowing to the product at the
minimum level.
When you are not using the product for a long time, make sure you unplug the power cord from the wall AC outlet.
Make sure to discard used batteries according to local regulations.
• Keep batteries away from children. A child could
accidentally swallow a battery. Failure to observe this may
also cause inflammation due to battery fluid leaks.
• Do not put batteries in a pocket or bag, or carry or store
them together with pieces of metal. Batteries kept in such
condition could short, burst, or leak, causing a fire or injury.
If you notice any abnormality
• If any of the following problems occur, immediately turn off
the power switch and disconnect the power plug from the
outlet. If you are using batteries, remove all batteries from
the product.
Finally have the device inspected by Yamaha service
personnel.
- The power cord or plug becomes frayed or damaged.
- Unusual smells or smoke are emitted.
- Some object, or water has been dropped into the
product.
- There is a sudden loss of sound during use of the product.
- Cracks or other visible damage appear on the product.
Handling
• Do not insert foreign materials such as metal or paper into
any openings or gaps of the product. Failure to observe this
may cause a fire, electric shocks, or malfunctions.
• Do not rest your weight on, or place heavy objects on the
product, and do not use excessive force on the buttons,
switches or connectors.
• Do not use the product or headphones for a long period of
time at a high or uncomfortable volume level, since this can
cause permanent hearing loss. If you experience any
hearing loss or ringing in the ears, consult a physician.
• Remove the power plug from the AC outlet before cleaning
the unit. Failure to observe this may cause electric shocks.
