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 a specified period of time. In the default settings, the power will be turned off if this instrument is not operated for 30 minutes. If you wish to disable the Auto Power Off function, turn the power on while holding down the lowest key on the keyboard. An "Auto power off disabled" message appears briefly and Auto Power Off is disabled. The setting is retained even if the power is turned off. The amount of time that elapses before the power is automatically turned off can be set by the following operation. [UTILITY]  Select "01:General" with Cursor [V] button  [ENTER]  Select "AutoOff" with Cursor [E] button, then change the value with [DATA] dial  [STORE] NOTICE • Depending on the instrument status (for example, the settings have been modified but not yet stored), the power may not turn off automatically, even after the elapse of the specified period of time. Always turn off the power manually when the instrument is not in use. • When the instrument is not operated for a specified period of time while connected to an external device such as an amplifier, speaker or computer, make sure to follow the instructions in the Owner's Manual to turn off the power to the instrument and the connected devices, in order to protect the devices from damage. If you do not want the power to turn off automatically when a device is connected, disable Auto Power Off. • When Auto Power Off is set to "off," the value will be retained even if the backup data saved on another device is loaded to the instrument. When Auto Power Off is set to something other than "off," the value will be overwritten with loaded data. • Keep in mind that the amount of time that elapses before the power automatically turns off is reset to 30 minutes if you execute the Factory Set function (page 15). NOTE • The setting time is approximate. • To turn the power on after Auto Power Off has been executed, press the Standby/On switch once to set it to Standby, and then press it again to set to On.
