3e. OptiMains® Protection for Excessive Under/Over-Voltages

The CD-77 is fitted with the OptiMains® system to condition and adjust the incoming mains supply for the best operation under all normal mains conditions (including situations that will cause audible problems without Opti- Mains®).

With almost every country throughout the world, instances inevitably arise where fluctuations in the main elec- tricity 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 ex- ceed 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.

Power OFF the 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.
