By default, it will turn off the instrument after 30 minutes if it is not operated in any way. Disabling the Auto Power-Off function To disable the Auto Power-Off function, either set the corresponding Function parameter to "Off" or turn on the instrument while holding down the left-most key on the keyboard. When disabled in this way, the instrument will not turn off automatically. Left-most key Changing the Auto Power-Off time 1 Press the [FUNCTION] button to access the Func- tion parameters. 2 Press the [FUNCTION] button repeatedly until Func- tion parameter F8.8 is shown. Then, press the [-/NO] or [+/YES] button to select that Function parameter. 3 Set the desired Auto Power-Off time using the [-/NO] and [+/YES] buttons. • Available settings: OFF, 5, 10, 15, 30, 60, and 120 minutes • Default setting: 30 minutes 4 Press the [FUNCTION] button to return to the previ- ous screen. NOTE • Before the Auto Power-Off function turns off the instrument, unsaved data will be automatically backed up. See page 46 for details of the data backed up at this time. NOTICE • In certain modes of operation, the Auto Power-Off function will not turn off the digital piano when the set time has elapsed. We recommend, therefore, that you always turn off the instrument manually when you are finished using it. • If your digital piano is connected to other equipment such as amplifiers, speakers, or a computer but you do not intend to use it for some time, we recommend that you turn off all devices as described in their owner's manuals. Doing so eliminates the risk of damage to the other equipment. If you do not want the instrument to turn off automatically when connected to other equipment, disable the Auto Power-Off function. If you are going to use your instrument in a live music situation such as on-stage, we recommend that you disable the Auto Power-Off function. (See page 37, 39.)
