ANSWER
This indicates that the CS ONE does not work as it should.
This indicates that there is either a faulty connection to the battery or the
battery being charged is faulty.
The circling white light on the CS ONE shows that the charger seeking /
analyzing the battery. If this process takes longer than 60 seconds, it is
an indication of poor contact between the battery and the charger - or a
battery drained too low (<1,5V for lead acid and a lithium that has closed
down, Under Voltage Protection).
It means that the battery does not have enough power to start the vehicle. Continue to charge until the 'START' indicator becomes permanently lit.
