What to do if nothing happens when pressing LAYER or SPLIT button on Casio CTK-900 Electronic Keyboard?

If nothing happens when you press the LAYER or SPLIT button on your Casio Electronic Keyboard, one or more of the melody channels (2 through 4) might be turned off, or their volume settings could be too low. Also, the keyboard might be in record standby, or the SMF Player Mode might be in use. To resolve this, use the Mixer to turn on Channels 2 through 4 and raise their volume settings. Note that the LAYER and SPLIT buttons are disabled during recording and record standby, and they are not available while the SMF Player Mode is in use.
