Starting Up

WARNING
Make sure your Tyros4 is rated for the AC voltage
supplied in the area in which it is to be used (as
listed on the bottom). Connecting the unit to the
wrong AC supply can cause serious damage to the
internal circuitry and may even pose a shock haz-
ard!
WARNING
Use only the AC power cord supplied with the
Tyros4. If the supplied cord is lost or damaged and
needs to be replaced, contact your Yamaha dealer.
The use of an inappropriate replacement can pose
a fire and shock hazard!
WARNING
The type of AC power cord provided with the Tyros4
may be different depending on the country in which
it is purchased (a third prong may be provided for
grounding purposes). Improper connection of the
grounding conductor can create the risk of electri-
cal shock. Do NOT modify the plug provided with
the Tyros4. If the plug will not fit the outlet, have a
proper outlet installed by a qualified electrician. Do
not use a plug adapter which defeats the grounding
conductor.
CAUTION
In order to avoid possible damage to the speakers
or other connected electronic equipment, always
switch on the power of the Tyros4 before switching
on the power of the amplified speakers or mixer
and amplifier. Likewise, always switch off the
power off the Tyros4 after switching off the power of
the amplified speakers or mixer and amplifier.
CAUTION
Even when the power switch is turned off, electric-
ity is still flowing to the instrument at the minimum
level. When you are not using the instrument for a
long time, make sure you unplug the power cord
from the wall AC outlet.
