Cycle selector is not working on Dolphin Liberty 300 and 400

Step by step.

Make sure that the Cycle Selector feature is activated correctly:

1. Press the Power (ON) button. After the battery LED lights up, press and hold the Power (ON) button for 3-6 seconds.
2. Let go of the Power (ON) button when the purple LED blinks 3 times. Place the robot in the pool, and it is supposed to start working within 30 seconds.
