MODEL 1984 Cordia, Tredia, Starion
The RX-390 AM/FM stereo radio is equipped with an electronic volume control. Like other radios with electronic tuning, even the briefest period of low battery voltage due to extremely cold weather, battery discharged from headlights left on, after extended storage, etc. can cause abnormal behavior, such as:
^ Volume cannot be changed by pushing the volume (+) or (-) buttons.
^ No sound at all.
^ Sound on only one channel.
^ Sound level varies even when volume controls are not pressed.
The above conditions can occur even after battery system voltage has been brought back up to normal. Any or all of these conditions are easily corrected by first turning the ignition switch off and then disconnecting the negative (-) battery terminal for a minimum of 60 seconds to erase the memory (ROM) in the radio and restore normal operation.
