Auto Power Off
To prevent unnecessary power consumption, this instrument features an Auto Power Off
function that automatically turns the power off if the instrument is not operated for
approximately 30 minutes. If you do not want to use the Auto Power Off function, disable
the function as described below. The setting (disabled or enabled) is retained even if the
power is turned off.
Disabling Auto Power Off
Turn the power of the instrument off. Then, while holding down
the lowest key, press the [
power again so that the [REC] indicator flashes three times,
indicating that the Auto Power Off function has been disabled.
You can also disable the Auto Power Off function without turning
the power off, by simultaneously holding down [DEMO/SONG]
and [PIANO/VOICE] and pressing the A 5 key.
Re-enabling Auto Power Off
To enable the Auto Power Off function again, simultaneously hold
down [DEMO/SONG] and [PIANO/VOICE] and press the A5 key.
Since this instrument is equipped with two [PHONES] jacks, you can
connect two sets of standard stereo headphones. If you are using only
one set of headphones, insert a plug into either jack, which
automatically shuts off the speakers.
Do not use headphones at a high volume for an extended period of
time; doing so may cause hearing loss.
