Please try to avoid placing the console close/on any power distribution units or power amplifiers. When using an external power supply, it should be located as far as possible from the console. The power supply should be set for the voltage supply available in your area and plugged into the mains socket using the cable provided with the ground/screen connector properly connected. The Typhoon should only be operated with the power supply connected to ground via the ground in the mains connector. The use of alternative power supplies may cause damage and void the warranty. The power supply should never be operated with the mains earth disconnected Please note that the power supply contains DANGEROUS VOLTAGES, ...
