MS40DR Owner’s Manual
PRODUCT SAFETY MARKINGS: Yamaha electronic
products may have either labels similar to the graphics
shown below or molded/stamped facsimiles of these graph-
ics on the enclosure. The explanation of these graphics
appears on this page. Please observe all cautions indicated
on this page and those indicated in the safety instruction sec-
tion.
The exclamation point within the equi-
lateral triangle is intended to alert the
user to the presence of important operat-
ing and maintenance (servicing) instruc-
tions in the literature accompanying the
product.
The lightning flash with arrowhead sym-
bol, within the equilateral triangle, is
intended to alert the user to the presence
of uninsulated “dangerous voltage”
within the product’s enclosure that may
be of sufficient magnitude to constitute a
risk of electrical shock.
IMPORTANT NOTICE: All Yamaha electronic products
are tested and approved by an independent safety testing
laboratory in order that you may be sure that when it is prop-
erly installed and used in its normal and customary manner,
all foreseeable risks have been eliminated. DO NOT modify
this unit or commission others to do so unless specifically
authorized by Yamaha. Product performance and/or safety
standards may be diminished. Claims filed under the
expressed warranty may be denied if the unit is/has been
modified. Implied warranties may also be affected.

rect at the time of printing. However, Yamaha reserves the

ENVIRONMENTAL ISSUES: Yamaha strives to produce
products that are both user safe and environmentally
friendly. We sincerely believe that our products and the pro-
duction methods used to produce them, meet these goals. In
keeping with both the letter and the spirit of the law, we
