Connecting the Power Cord
Carefully read the following instructions and warnings before
connecting the power cord.
1. Connect the supplied power cord to the [AC IN] connector
on the instrument’s bottom panel. For an illustration of the
location of the
[AC IN] connector, see “Panel Controls and
Terminals” (page 10).
2. Connect the other end of the power cord to an AC outlet.
Make sure your H11 meets the voltage requirement for the
country or region in which it is being used.
In some areas, a plug adaptor may be provided to match the
pin configuration of the AC wall outlets in your area.
WARNING
Make sure your H11 is rated for the AC voltage supplied in the area in which it is to be used (as listed
on the bottom panel). Connecting the unit to the wrong AC supply can cause serious damage to the
internal circuitry and may even pose a shock hazard!
WARNING
Use only the AC power cord supplied with the H11. 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!
Turning the Power On
Press the [POWER] switch.
The power indicator located above the [MASTER VOL-
UME] control lights up.
To turn off the power, press the [POWER] switch again.
CAUTION
Never interrupt the power supply while the instrument is load-
ing data from a USB flash memory! Doing so can result in loss
of data.
CAUTION
Even when the instrument is turned off, electricity is still flow-
ing to the instrument at the minimum level. When you are not
using the instrument for a long time or during electrical
storms, make sure you unplug the AC power plug from the
wall AC outlet.
Setting the Volume
Initially set the [MASTER VOLUME] control about halfway
between the “MIN” and “MAX” settings. Then, when you start
playing, re-adjust the
[MASTER VOLUME] control to the most
comfortable listening level.
CAUTION
Do not use the instrument at a high volume level for a long period of time, or your hearing may be damaged.
TERMINOLOGY VOLUME: The volume level of the entire keyboard sound.
TIP You can also adjust the [PHONES] output level using the [MASTER VOLUME] control.
