What is the purpose of pressing the yellow button on the ePAR twice?

Pressing the yellow button on the ePAR (Emergency Personal Alert Radio) twice serves the specific function of resetting the PASS (Personal Alert Safety System) alert. The PASS device is critical for ensuring the safety of firefighters by providing an audible alert if a firefighter becomes motionless or is in need of assistance. When the yellow button is pressed twice, it effectively silences the alarm that has been triggered by the PASS device, allowing personnel to regain control of the situation without the distraction of the alarm. Understanding this function is vital for maintaining communication and safety during emergency operations, particularly in high-stress environments like firefighting.

The other functions of the yellow button include specifically activating alerts or turning the unit off, but those are not performed by pressing the button twice; each has its own dedicated action. Knowing how to properly reset the PASS alert ensures that firefighters can manage their safety systems efficiently in the field.
