Make all necessary connections BEFORE turning the power on.
You can connect the PHONES/OUTPUT jack to a set
of headphones, keyboard amplifier, stereo system,
mixer, tape recorder, or other line-level audio device
to send the instrument’s output signal to that device.
The internal speakers are automatically shut off when
a plug is inserted into this jack. The PHONES/OUT-
PUT jack also functions as an external output.
The sustain function lets you produce a natural sustain
as you play by pressing an optional footswitch. Plug
the Yamaha FC4 or FC5 footswitch into the SUS-
TAIN jack and use it to switch sustain on and off.
Turn down the volume by turning the [MASTER
VOLUME] control to the left and press the [ ]
(Standby/On) switch to turn on the power. While
playing the keyboard, adjust the volume level by using
the [MASTER VOLUME] control. Pressing the [ ]
(Standby/On) switch again turns the power off.
To prevent unnecessary power consumption, this instru-
ment features an Auto Power Off function that automati-
cally turns the power off if the instrument is not used for
approximately 30 minutes.
To disable the Auto Power Off function
While holding down the lowest key, press the [ ]
(Standby/On) switch to turn on the power. Alternately
select “Off” in the Function settings (page 30 Func-
tion 024).
Connecting headphones and
external audio equipment
• You can set the Master equalizer (EQ) which is provided to
give you the best possible sound when listening through dif-
ferent reproduction systems. The Master equalizer (EQ) can
be set in the Function settings (page 29 Function 013).
• Avoid listening with the headphones at high volume for
long periods of time; doing so may not only result in ear
fatigue, it may be damaging to your hearing.
• To prevent damage to the speakers, set the volume of the
external devices at the minimum setting and turn power off
the devices before connecting them. Failure to observe
these precautions may result in electric shock or equip-
ment damage. Also, be sure to set the volumes of all
devices at their minimum levels and gradually raise the vol-
ume controls while playing the instrument to set the
desired listening level.
Connecting a footswitch
• Make sure that the footswitch plug is properly connected to
the SUSTAIN jack before turning on the power.
• Do not press the footswitch while turning the power on. Doing
this changes the recognized polarity of the footswitch, result-
ing in reversed footswitch operation.
