Manual-Advance Mode - iRobot Roomba Scheduler Service Manual

o If any test FAILED:
MANUAL-ADVANCE mode is designed to be used for debugging particular sensors or actuators.
In this mode, the robot DOES NOT decide PASS/FAIL for each test number. The test does not
automatically advance, so sensors or actuators can be tested as many times as needed.
In MANUAL-ADVANCE mode:
• Use the CLEAN button to MANUALLY ADVANCE to the next built-in-test number.
• Use the SPOT button to go back to the previous built-in-test number.
• The POWER LED will always be GREEN.
• There is no pass or fail. If you advance past the last test number, the test number will wrap
around to the first test.
The following chart describes how to use each built-in-test number. To PASS the built-in-test in
AUTO-ADVANCE mode, the user must perform the actions EXACTLY AS DESCRIBED.
