Precautions - Yamaha MU5 Owner's Manual

Your MU5 will give you years of reliable service if you follow the simple
precautions below:
Keep the instrument away from locations where it is likely to be
exposed to high temperatures (such as direct sunlight) or humid-
ity. Also avoid locations which are subject to excessive dust
accumulation or vibration which could cause mechanical damage.
Use only the recommended PA-3, PA-4 or PA-40 Power Adaptor
for supplying power to the instrument. Use of another adaptor
may cause serious damage to the instrument or the adaptor itself.
(Never use the PA-3B.)
To prevent damage to the instrument and other connected equip-
ment, always turn off the power prior to connecting or discon-
necting cables. Also, turn the power off when the instrument is
not in use, and disconnect the power adaptor during electric
storms.
Although the instrument has been constructed to withstand the
rigors of normal use for optimum sturdiness and reliability, avoid
subjecting it to strong physical shocks (such as dropping or
hitting it). Since the MU5 is a precision-made electronic device,
also avoid applying excessive force to the various controls.
When moving the instrument, first unplug the power adaptor and
all other cables to prevent damage to cords and jacks. Always
unplug cables by gripping the plug firmly, not by pulling on the
cable.
