Power On Alert

Keyboard keys light to alert you if you leave power on and do not perform any operation for about 6 minutes. Note that keys light only, and no sound is produced. When this happens, press any button or keyboard key to clear the power on alert.

NOTE

Power on alert operates only when you are powering the keyboard using the AC adaptor. It does not operate when you are using batteries.

To turn off power on alert

1Press the FUNCTION button a number of times until “DEMO 2” appears on the display.

2Use the [+] and [–] buttons to change the setting to “oFF”.

3Press the FUNCTION button to clear the setting screen from the display.

Memory Contents

Even when the keyboard is turned off, song memory contents are retained as long as power is being supplied to the keyboard.

Unplugging the AC adaptor when batteries are not loaded or when batteries are dead cuts off the power supply. This causes all keyboard settings to be initialized to the initial factory defaults, and clears all data stored in memory.

Power Requirements

Note the following precautions whenever you want to ensure that current keyboard settings and memory contents are not lost.

Make sure the keyboard is being supplied power through the AC adaptor before replacing its batteries.

Before unplugging the AC adaptor, make sure that fresh batteries are loaded in the keyboard.

Make sure that keyboard power is turned off before replacing batteries or unplugging the AC adaptor.
