Casio LK-40 - Manual (Page 18)

E-16
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.
■ 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.
Note
• Auto Power Off is disabled (it does not function) when you are using the AC adaptor
to power the keyboard.
■ 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 disable Auto Power Off and power on alert
Hold down the TONE button while turning on the keyboard to disable Auto Power
Off and power on alert.
• When these functions are turned off, the keyboard does not turn off automatically
and no alert is performed no matter how long it is left with no operation being
performed.
• Auto Power Off and power on alert are enabled again when you manually turn off
power and then turn it back on again.
