Connect the 12V DC power supply either to the back panel supply connector
marked DC IN, or terminals marked DC IN + and DC IN –.
Warning
? If you use an adapter other than the recommended one, do not exceed the
nominal supply voltage value of 12V. Also make sure that the supply voltage
polarity is correct. Exceeding nominal values and/or incorrect connection may
lead to irreversible damage of the equipment.
