The LEDs can glow green, amber or red. Typically, greenindicates normal operation, amber indicates a warning, and red indicates a fault or error.Figure 1.1: Alarm/Status LEDsWhen an LED is:• green - transmitter is on, with no known faults.• amber - a fault is present that may cause a reduction in RF power, but the transmitter is stillproducing RF power.• red - a fault is present and the transmitter is not producing RF power.When a fault is present, the transmitter may still produce an RF output.
