*1: When the power switch is turned from off to on (ACC), the mobile wireless charger cradle assembly checks the charging stop signal for 1 second. If the charging stop signal is not 4 V or higher for 0.8 seconds or more within 1 second continuously, the mobile wireless charger cradle assembly determines that there is an open circuit in the charging stop signal circuit, blinks the indicator amber (pattern 1), and stops operation until the next time the power switch is turned on (ACC).
