To shut down the TIC Vapor Detector/Gas Monitor Kit, which button must be pressed and for how long?

• A. MODE button for 3 seconds
• B. MODE button for 5 seconds
• C. MODE button for 10 seconds
• D. POWER button for 5 seconds

Answer: (B)

Holding the MODE button for five seconds is the intentional shutdown action for the TIC Vapor Detector/Gas Monitor Kit. The design uses a deliberate hold on MODE to prevent accidental power-offs during normal use, so a quick tap won’t shut it down and a five-second hold cleanly initiates the shutdown sequence. The POWER button isn’t the commanded shutdown path in this setup, since the device’s shutdown workflow is tied to a MODE-button hold. In short, press and hold MODE for five seconds to power down.
