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 dis-
able 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.

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 automati-
cally by Auto Power Off remain in effect when you next turn power
back on.
Main Keyboard Settings
Main keyboard settings are: tone number, layer, split, split
point, touch response, rhythm number, tempo, accompani-
ment volume, General MIDI mode on/off, accomp MIDI
OUT on/off, Assignable jack setting, keyboard channel, and
Song Bank number.
Memory Contents
In addition to the above settings, data stored using the memory func-
tion 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 batter-
ies are dead cuts off the keyboard's electrical power supply. This caus-
es 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 bat-
teries or unplugging the AC adaptor.
