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.

❚ NOTE ❚

Auto 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.

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

Settings and Memory Contents

The following describes what happens to settings and memory contents when power is turned off.

Settings

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

Main Keyboard Settings

Tone number, rhythm number, touch response on/off, touch response sensitivity, accompaniment mode, DSP on/off, DSP selection, assignable jack setting, tempo, Mixer parameters (tone, volume, pan, effect send, channel on/off, accompaniment volume), keyboard channel, General MIDI on/off, Pitch Bend range, accomp MIDI out on/off, MIDI in chord judge on/off, registration bank, layer on/off, auto harmonize on/off, split on/off, split point, Song Sequencer settings (song number, metronome, quantize), Pattern Sequencer settings (metronome, quantize), sound range shift on/off, contrast setting, SMF playback settings (WK-1800 only)

Memory Contents

In addition to the above settings, Registration, Song Sequencer, Pattern Sequencer, and Synthesizer memory contents are also retained when power is turned off.

Power Requirements

The keyboard comes with a built-in lithium battery that supplies power to the memory to retain Song Sequencer, Pattern Sequencer and other data while keyboard power is turned off. If the power of the lithium battery is low, turning off keyboard power can result in deletion of all data stored in its memory.

The normal life of the original battery is five years from the time it is loaded at the factory. Due to time spent in transit and storage, the original battery probably will not provide a full five years of service life. It is up to you to contact your nearest CASIO service provider about having the lithium battery replaced periodically.

Note that you will be charged separately for lithium battery replace- ment.

To protect against loss of valuable memory data, we strongly suggest that you use either of the following methods to back it up.

•Perform a MIDI dump of the data to a computer or other external device for storage. See “Bulk Sending Keyboard Data” on page E- 65 for details.

•Save the data to diskette (WK-1800 only). See “Using the Floppy Disk Drive” on page E-67 for details.

To initialize the keyboard and delete all data

You can either fully initialize the keyboard or initialize parameters only.

Full Initialization

Use this procedure to return all keyboard settings to what they were when you purchased it. Note that this procedure clears all data from memory.

1. While holding down the ENTER button, turn on keyboard power.R e s e t ? ��

2. Press YES to initialize the keyboard or NO to turn on power without changing any settings.

•The above procedure restores registration memory to its fac- tory default contents. Any setup data stored in registration memory is deleted by the above procedure.

Parameter Initialization

Use this procedure to return all keyboard settings to what they were when you purchased it. Note that this procedure does not affect user tones, user rhythms, registration memory contents, and display contrast settings.

While keyboard power is on, press the [+], [–], and ENTER buttons at the same time.
