Thermistors
HDCU3300 is provided with positive thermistors for
power circuit. If an overcurrent flows in a positive ther-
mistor or it heats up to a certain degree with the increase of
the ambient temperature, its internal resistance increases
sharply to limit the current flowing in the circuit. When a
thermistor is activated, turn off the power and check the
circuit of the unit. After the cause of the problem is
removed and the device cools down, turn on the power
again. The unit will work normally. It takes about one
minute for the device to cool down.
