Test the Functions
Wrap the seat with plastic wrap to prevent water from spraying from the toilet
during testing.
The seat is designed not to function without an occupant. To activate the seat
controls for testing purposes, when facing the toilet, place your hand or a damp
wash cloth on the right side of the seat approximately 1/3 from the front of the
seat (sensor area).
Proceed to the "Keypad and Panel Diagram" and "Operation" Sections to test
the various seat functions.
