PHONES/OUTPUT Jack
For connecting a set of stereo headphones with a
stereo mini plug. This jack also functions as an
external output for sending the audio signal of this
instrument to external audio equipment.
The speakers of the instrument are automatically
shut off when a headphones plug, etc. is inserted
into this jack.
• Before using the headphones, be sure to set the volume of the instrument at the minimum level. Then gradually raise the
volume while playing the instrument, for your ear comfort and safety.
CAUTION
Rear
• Do not use the instrument or headphones for a long
period of time at a high or uncomfortable volume level,
since this can cause permanent hearing loss.
• Before connecting the instrument to other electronic com-
ponents, make sure to set all volume levels to minimum,
then turn off the power off all the components. Otherwise,
damage to the components or electrical shock may occur.
• To avoid possible damage to the external device, first turn
on the power to the instrument, then to the external
device. When turning off the power, do so in reverse
order: first turn off the power to the external device, then
to the instrument.
