What are the two modes of the URT-33C/M Personal Locator Beacon?

The URT-33C/M Personal Locator Beacon operates in two distinct modes: Timed and Continuous.

In the Timed mode, the beacon transmits a distress signal at predetermined intervals, allowing for a more controlled and efficient use of battery life. This is particularly useful in situations where continuous transmission is unnecessary, as it conserves power for longer operational duration.

On the other hand, the Continuous mode allows the beacon to transmit a distress signal constantly. This persistent signal is critical in search and rescue scenarios, ensuring that rescuers can locate the beacon quickly and accurately, particularly in environments where visibility is low or conditions are harsh.

This dual functionality enhances the utility of the URT-33C/M in diverse operational contexts, allowing aircrew to select the mode that best suits their situation.
