303e. OptiMains® Protection for Excessive Under/Over-VoltagesOne of the core circuits of the CD-77 is the OptiMains® system which will condition and adjust the incomingmains supply for the best operation under all normal mains conditions (including situations that will cause audibleproblems without OptiMains®).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 properlyserved. 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 internalparts 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 eO p e r a t i n g R a n g e !Power OFF the AMR component and wait at least 5 minutes. If and when the mains electricity has beendeemed to have returned to normal (such as during a brown out and the lights have dimmed but have returned tonormal brightness) then power up your AMR component as per the manual’s instructions.If there are any questions/doubts, please contact AMR directly or your nearest AMR distributor/dealer.In the event thereare excessivemains fluctua-tions......Optimains® willdetect andprotect |
