What does the Lamp Test switch verify?

Explanation:
The Lamp Test switch is used to verify the indicator lights on the Remote Control Unit (RCU). When you activate this test, all the RCU lamps illuminate to confirm that the lights themselves, their wiring, and the power supply to the RCU are working properly. If any lamp fails to light, it signals a fault in the indicator circuit, helping you spot issues before the equipment is relied on in operations. This test specifically checks RCU Lights and is not for ATIS audio playback, recorder status, or broadcast frequency, which are verified by other checks or controls.
