2. Heart Beat: Flashes to indicate proper
microprocessor operation.
3. Battery Connect (BAT CON): Illuminates on AC
failure when batteries are powering the supply.
4. Battery Low (BAT LOW): Illuminates when
batteries have a high internal resistance [battery
cell failure] (within 120 seconds).
5. Battery O/C (BAT O/C): Illuminates when
