Code A04-04 - SYSTEM MEMORY ERROR / STORED DATA WRITE ERROR
An error occurred during a WRITE attempt to SDRAM saved data.
CAUSE:
1. If the controller is located in an electric or magnetic noise field.
2. SDRAM chip has malfunctioned.
RECOVERY:
1. Verify that the controller is not located near any high voltage transient power sources. Relocate as
required and reinitialize the system.
2. Turn control power off to the unit for at least 5 minutes then re-apply power.
3. Replace controller.
