Two MASTER CAUTION lights on the instrument panels indicate that one or more of the caution capsules have illuminated. On the pilot instrument panel, the caution light is above the airspeed indicator. On the copilot instru- ment panel, it is above the altimeter. Movable NVG filters are attached to the instrument pan- els to the left of each light. For NVG operations, the filters can be rotated over the two MASTER CAUTION lights making the lights NVG compatible. After the MASTER CAUTION has illuminated and the condition noted, the pilots should extinguish the MASTER CAUTION light by pressing (PUSH TO RESET) the face of the light. The MASTER CAUTION light is then ready to indicate a sub- sequent malfunction of a different system. Once the malfunction is corrected, the affected caution capsule will extinguish. The HEATER HOT capsule is an exception (Refer to Section X). If either generator is cycled OFF then ON while another caution capsule is lit, the MASTER CAUTION light may remain illuminated af- ter the generator comes back on and the associated GEN OFF capsule extinguishes. If this occurs, press to extinguish the MASTER CAUTION light. Figure 2-14-6. Master Caution /Advisory Panel 714A
