Power Supply

Settings and Memory Contents

Settings

Tone, rhythm, and other “main keyboard settings” in effect when power is turned off manually with the POWER button or automatically by Auto Power Off remain in effect when you next turn power back on.

Main Keyboard Settings

Main keyboard settings are: layer, split, split point, touch response, rhythm number, rhythm tempo, accompaniment volume, layered tone, split tone, layered split tone, General MIDI mode on/off, accomp MIDI OUT on/off, Assignable jack setting, keyboard channel, and voice fingering guide on/off.

Song Memory Contents

In addition to the above settings, data stored using the song memory function is also retained.

Electrical Power

The settings and memory data described above are retained as long as the keyboard is being supplied with electrical power. Unplugging the AC adaptor when batteries are not loaded or when loaded batteries are dead cuts off the keyboard’s electrical power supply. This causes all settings to be initialized to their 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.
