11.  Mains Voltage Selector 

This is factory set to your country’s mains voltage specification. Do not attempt to adjust this 
as this may lead to permanent damage to the product and even the risk of fire.  There is a clear 
plastic cover over the selector to prevent accidental adjustment.

The LED on the top of the cabinet indicates whether the unit is in standby mode or operational.  It 
will be illuminated red when in standby, and green when operational.
