Precautions
Your MU50 will give you years of reliable service if you follow the simple
precautions below:
LOCATION
Keep the instrument away from locations where it is likely to be exposed to
high temperatures (such as direct sunlight) or humidity. Also avoid loca-
tions which are subject to excessive dust accumulation or vibration which
could cause mechanical damage.
USE THE CORRECT POWER ADAPTOR
Use only the recommended PA-1207 Power Adaptor for supplying power
to the instrument. Use of another adaptor may cause serious damage to the
instrument or the adaptor itself.
MAKE SURE POWER IS OFF WHEN MAKING OR REMOVING
CONNECTIONS
To prevent damage to the instrument and other connected equipment, al-
ways turn off the power prior to connecting or disconnecting cables. Also,
turn the power off when the instrument is not in use, and disconnect the
power adaptor during electric storms.
HANDLE THE INSTRUMENT WITH CARE
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 MU50 is a
precision-made electronic device, also avoid applying excessive force to the
various controls. When moving the instrument, first unplug the power adap-
tor and all other cables to prevent damage to cords and jacks. Always un-
plug cables by gripping the plug firmly, not by pulling on the cable.
CLEAN WITH A SOFT, DRY CLOTH
Never use solvents such as benzine or thinner to clean the instrument, since
these will damage the cabinet finish or dull the keys. Wipe clean with a
soft, dry cloth. If necessary, use a soft, clean, slightly moistened cloth —
making sure to wipe the case off again with a dry cloth.
