Connecting Headphones (Phones/Output Jack); Connecting A Footswitch (Sustain Jack); Turning The Power On - Yamaha PSR-E423 Owner's Manual

Make all necessary connections below BEFORE turning the power on.
Connecting Headphones
(PHONES/OUTPUT Jack)
Any pair of stereo headphones with a 1/4" stereo
phone plug can be plugged in here for convenient
monitoring. The speakers are automatically shut off
when a plug is inserted into this jack.
The PHONES/OUTPUT jack also functions as an
external output. You can connect the PHONES/OUT-
PUT jack to a keyboard amplifier, stereo system,
mixer, tape recorder, or other line-level audio device
to send the instrument's output signal to that device.
WARNING
• 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.
CAUTION
• To prevent damage to the speakers, set the volume of the
external devices at the minimum setting before connecting
them. Failure to observe these cautions may result in elec-
tric shock or equipment damage. Also, be sure to set the
volumes of all devices at their minimum levels and gradu-
ally raise the volume controls while playing the instrument
to set the desired listening level.
Connecting a Footswitch
(SUSTAIN Jack)
The sustain function lets you produce a natural sustain
as you play by pressing a footswitch. A Yamaha FC4
or FC5 footswitch plugged into this jack can be used
to switch sustain on and off.
NOTE
• The sustain function does not affect split voices.
• 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 foot-
switch, resulting in reversed footswitch operation.
