What audible indication confirms the iTIC has been activated?

• A. A single beep
• B. Two beeps
• C. Three beeps
• D. No beeps

Answer: (B)

Two quick beeps are the signal that the iTIC is active. That distinct sound is designed to be clear in smoky, low-visibility conditions so you can confirm immediately that the device is powered up and ready to provide thermal imaging. Other audible patterns or no sound would indicate a different status or that the iTIC isn’t activated, which means you wouldn’t have the expected thermal view. If you don’t hear the two beeps, re-activate the iTIC following the procedure to ensure you have the essential information you need.
