3c. 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 automatically will switch off the mains power to the internal parts of equipment to prevent any damage from occuring.

If the display reads:

...OptiMains® will detect and protect

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.
