1.3 Before powering up...
The mains voltage can be either nominally 115V or 230V without the need for voltage
selection.
The power connector `block' houses the ON/OFF switch, the fuse 2A(T) (Slow blow) and
the mains inlet - see figure 2.

The unit should NOT be powered up or down with a device in any of the sockets.
Wait a minimum of 5 seconds after powering down, before powering back up.
