Memory Contents
Song Memory Contents
Data stored using the song memory function is retained.
Electrical Power
The song memory data is 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 clears all data stored in memory.
Power Requirements
Note the following precautions whenever you want to ensure
that current song 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.
