If the equipment malfunctions, this may be because an electrostatic discharge or AC line interference has corrupted the information in the equipment memory circuits. Therefore:
-disconnect the plug from the AC line supply
-after waiting at least three minutes, reconnect the plug to the AC line supply
-
Memory backup
•In case a power outage occurs or the power cord is accidentally unplugged, the SR7500 is equipped with a backup function to prevent memory data such as the preset memory from being erased.
