Power Supply

Auto Power Off

When you are using battery power, keyboard power turns off automatically whenever you leave it on without performing any operation for about 6 minutes. When this happens, press the POWER button to turn power back on.

ŠAuto Power Off is disabled (it does not function) when you are using the AC adaptor to power the keyboard.

To disable Auto Power Off

Hold down the TONE button while turning on the keyboard to disable Auto Power Off.

ŠWhen Auto Power Off is disabled, the keyboard does not turn off automatically no matter how long it is left with no operation being performed.

ŠAuto Power Off is automatically enabled whenever you turn on keyboard power.

Settings

Tone, rhythm, and other “main keyboard settings” in effect when you turn off the keyboard manually by pressing POWER button or when Auto Power Off turns off power are still in effect the next time you turn power back on.

Main Keyboard Settings

Turning Off the Keyboard

ŠBe sure to press the POWER button to turn off power and make sure that the LCD backlight is off before disconnecting the AC adaptor or doing anything else.

ŠNever disconnect the AC adaptor while the keyboard is turned on or try to turn off power using any other technique besides pressing the POWER button. Doing so can cause the contents of the keyboard's Flash memory to become corrupted. Strange keyboard operation and abnormal startup when power is turned on are symptoms of corrupted Flash memory contents. See “Troubleshooting” on page E-83 for more information.

ŠNever press the POWER button while the following message is on the keyboard’s display.

(message) “Pls Wait” or “Bulk In”

Turning off the keyboard while the above message is on the display can cause user data (user tones, song memory data, etc.) currently stored in keyboard memory to become corrupted. Once corrupted, you may not be able to recall the data again.

Memory Contents

In addition to the above settings, data stored in the Registration Mode and Song Memory Mode is also retained when keyboard power is turned off.

Saving Setups and Memory Contents

About Flash memory

Your keyboard comes with built-in Flash memory, which can continue to hold data even when electrical power is totally cut off. This means that even after batteries go completely dead, you can attach the AC adaptor, turn on power, and still recall data stored in memory.

ŠWhen running under battery power, be sure to replace batteries as soon as possible after the first signs of low battery power (dim power indicator lamp, dim display characters, etc.) Though the keyboard’s Flash memory is non-volatile (which means that data is not lost when power is interrupted), data can be lost if power suddenly fails while data is being written to flash memory*.

*While storing or deleting user data, while recording with the synthesizer, while transferring data from a computer, etc.

Initializing the Keyboard

Use the procedure on page E-75 to initialize the keyboard, which clears all memory data and returns settings to their initial factory defaults.
