4.6 OptiMains® Protection for Excessive Under/Over-Voltages
The AM-77 is fitted with the OptiMains® system to condition and adjust the incoming mains supply for best
operation under all normal mains conditions (including situations that will cause audible problems without Opti-
Mains® ).
In almost every country throughout the world, instances do arise where fluctuations in the main electricity exceeds
that of a correctly operating mains supply and any electrical item/product is no longer properly served. In the case
of extreme power surges, brown outs or other exceptional/unexpected conditions that exceed the safety margins,
the
OptiMains® system will automatically switch off the mains power to the internal parts of equipment to prevent
any damage from occuring.
If the display reads:
A C V o l t a g e O u t s i d e
O p e r a t i n g R a n g e !
Power OFF your AMR component and wait at least 5 minutes. If and when the mains electricity has been deemed
to have returned to normal (such as during a brown out and the lights have dimmed but have returned to normal
brightness) then power up your AMR component as per the manual’s instructions.
