Setting Up Auto Power Off Function 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 the Auto Power Off function When the instrument is turned off While holding down the A-1 key (the lowest key), press the [1] (Standby/On) to turn the instrument on.

Default setting: Enable A♯5 Highest key A5 Highest key Using Headphones 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. CAUTION Do not use headphones at a high volume for an extended period of time; doing so may cause hearing loss. Reproducing a natural sense of distance (Stereophonic Optimizer) The Stereophonic Optimizer gives you the feeling of playing an actual acoustic piano - even though you're listening through headphones. Normally, the sound comes out from headphones sounds very close to your ears. However, this Stereophonic Optimizer effect recreates a natural distance or the sense of physical space between your ears and the instrument, just as when playing an acoustic piano.
