PSS-A50 Owner’s Manual
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage
to the instrument or other property. These precautions include, but are not limited to, the following:
Use the specified USB power adaptor (page 7) only. Using the wrong
adaptor can result in damage to the instrument or overheating.
Do not connect the instrument to an electrical outlet using a multiple-
connector. Doing so can result in lower sound quality, or possibly
cause overheating in the outlet.
When removing the plug from the instrument or an outlet, always hold
the plug itself and not the USB cable. Pulling by the cable can damage
Remove the plug from the outlet when the instrument is not to be used
for extended periods of time, or during electrical storms.
Do not place the instrument in an unstable position where it might
accidentally fall over.
Before moving the instrument, remove all connected cables, to prevent
damage to the cables or injury to anyone who might trip over them.
When setting up the product, make sure that the AC outlet you are
using is easily accessible. If some trouble or malfunction occurs,
immediately turn off the power switch and disconnect the plug from the
outlet. Even when the power switch is turned 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 to disconnect the plug from the
wall AC outlet.
Before connecting the instrument 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 instrument to
set the desired listening level.
Do not insert a finger or hand in any gaps on the instrument.
Never insert or drop paper, metallic, or other objects into the gaps on
the panel or keyboard. This could cause physical injury to you or
others, damage to the instrument or other property, or operational
Do not rest your weight on, or place heavy objects on the instrument,
and do not use excessive force on the buttons, switches or connectors.
Do not use the instrument/device 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.
Always turn the power off when the instrument is not in use.
Even when the [ ] (Standby/On) switch is in standby status (display is off), electricity is still flowing to the instrument at the minimum level.
When you are not using the instrument for a long time, make sure you disconnect the plug from the wall AC outlet.
Make sure to discard used batteries according to local regulations.
