NOTICE
To avoid the possibility of malfunction/ damage to
the product, damage to data, or damage to other
property, follow the notices below.
Handling and maintenance
• Do not use the device in the vicinity of a TV, radio, AV
equipment, mobile phone, or other electric devices.
Otherwise, the device, TV, or radio may generate noise.
• Do not expose the device to excessive dust or vibration,
or extreme cold or heat (such as in direct sunlight, near a
heater, or in a car during the day), in order to prevent the
possibility of panel disfiguration, unstable operation, or
damage to the internal components.
• Do not place vinyl, plastic or rubber objects on the device,
since this might discolor the panel.
When cleaning the device, use a dry and soft cloth. Do not
use paint thinners, solvents, cleaning fluids, or chemical-
impregnated wiping cloths.
• Condensation can occur in the device due to rapid, drastic
changes in ambient temperature—when the device is

moved from one location to another, or air conditioning
is turned on or off, for example. Using the device while
condensation is present can cause damage. If there is
reason to believe that condensation might have occurred,
leave the device for several hours without turning on the
power until the condensation has completely dried out.
• The rubber feet included in this package can be attached to
the speaker to prevent slippage when it is to be used on a
slippery surface.
• Always turn the power off when the device is not in use.
Saving data
• This device has a built-in backup battery that maintains data in
internal memory even when the device's power is switched off.
The backup battery will eventually become depleted, however,
and when that happens the contents of the internal memory will
be lost.* To prevent loss of data be sure to replace the backup
battery before it becomes fully depleted. When the remaining
capacity of the backup battery becomes so low that it needs
to be replaced a "Low Battery" or "No Battery" message will
appear on the display during operation or when the device
is powered on. If either of these messages appears do not
turn off the power and immediately transfer any data you want
to save to a computer or other external storage device, then
have qualified Yamaha service personnel replace the backup
battery. The average life of the internal backup battery is
approximately 5 years, depending on operating conditions.
PA-7 2/2
