Auto Power Off; Power On Alert; To Disable Auto Power Off And Power On Alert - Casio LK-40 User Manual

Caution!
• For safety sake, be sure to unplug the AC adaptor from the wall outlet whenever
leaving the keyboard unattended for a long time (such as when leaving on a trip).
• Always turn off the keyboard and unplug the AC adaptor from the wall outlet when
you are not using the keyboard.
Important!
• Make sure that the keyboard is turned off before connecting or disconnecting the AC
adaptor.
• Using the AC adaptor for a long time can cause it to become warm to the touch. This
is normal and does not indicate malfunction.
I Auto Power Off
When you are using battery power, keyboard power turns off automatically when-
ever you leave it on without performing any operation for about 6 minutes. When
this happens, move the POWER/MODE selector to the OFF position and then back to
NORMAL, CASIO CHORD, or FINGERED to turn power back on.

operation for about 6 minutes. Note that keys light only, and no sound is produced.

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.
