SEC INDICATORS Mode

This mode allows user to display inputs and outputs which are not within optimum parameters but have not yet become faults. Secondary indicators are monitored by the DRB-II at all times after engine is selected in SELECT SYSTEM menu. When a secondary indicator is generated, DRB-II will emit 5 short beeps. If a secondary indicator becomes a hard fault, DRB-II red LED (light emitting diode) will glow.
