SOFT RESET - Hold down Record and press the bottom left button above the display.

SHOW SOFTWARE & HARDWARE CREDITS - Hold down Record and press Modes.

FILTER TUNING - Hold down Record and press Filter.

SHOW SOFTWARE VERSION (screen that comes up when turned on) - Hold down Record and press Master.

Hope this helps!
