Starting Up 5 After you finish using the instrument, turn off the power by pressing the [1] (Standby/On) switch for a second. The display, control buttons and power indicator are all turned off. CAUTION Even when the [1] (Standby/On) switch is in standby status, electricity is still flowing to the instrument at the minimum level. Remove the electric plug from the outlet when the instrument is not to be used for extended periods of time, or during electrical storms. NOTICE • Do not press any keys or pedals until the instrument has completely started up (the control buttons appear) after turning on the switch. Doing so may cause malfunction. • If you need to force-quit the instrument, hold down the [1] (Standby/On) switch for longer than three seconds. Keep in mind that the force-quit operation might cause data loss and damage to the instrument. 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. The amount of time that elapses before the power is automatically turned off is approximately 30 minutes by default; however, you can change the setting from [Utility] → [System] on Smart Pianist. NOTICE Any data which are not saved will be lost if the power automatically turns off. Make sure to save your data before this happens. Disabling Auto Power Off (simple method) Turn the power on while holding down the lowest key on the keyboard. The instrument starts up with the Auto Power Off function disabled. Lowest key (A-1) + NOTE You can enable/disable the Auto Power Off function by using the [FUNCTION] button (page 29). Adjusting the Master Volume To adjust the volume of the entire keyboard sound, use the [MASTER VOLUME] slider. Play the keyboard to check the sound while you adjust the volume. Increases the level. CAUTION Do not use the instrument for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. Intelligent Acoustic Control (IAC) Decreases the level. IAC is a function which automatically adjusts and controls the sound quality according to the overall volume of the instrument. Even when playing the instrument with the overall volume turned down, it permits both low sounds and high sounds to be clearly heard. IAC is effective only from the sound output of the instrument speakers. This function is set to on by default; however, you can turn it on or off, and set the depth from [Utility] → [Sound Setting] on Smart Pianist. P-S500 Owner's Manual 15
