Hard reset proberen
Hold down the    buttons at the same time. While still holding them, turn on the power.
On power up, press [Enter]. For Kurzweils with OS v1.0 only, the only way to do a hard reset is
to remove the batteries and let it sit for 30-60 minutes, then power back up. It will reset automatically.
A Soft Reset will reboot your K2000 and will not erase any RAM data, such as samples.
It is not as useful for corruption problems, but some people use it occasionally.
To do a Soft Reset on a K2000 model, press the [+/-]  [CLR] buttons
simultaneously with the K2000 on.
