To prevent the ETC anti-tamper switch from being triggered, you can tape over the switch before activation. The ETC anti-tamper switch is designed to prevent removal, which helps avoid the ETC device being shared among multiple vehicles. ETC (Electronic Toll Collection) is a non-stop electronic toll collection system, also known as an automatic road tolling system. It is commonly used on highways, toll bridges or tunnels, and certain urban roads to alleviate traffic congestion. ETC works by using dedicated short-range microwave communication between the vehicle's on-board unit (OBU) mounted on the windshield and the microwave antenna at the ETC toll lane. This system processes payments through computer networking technology with banks, allowing vehicles to pass through toll stations without stopping to pay tolls.
When installing ETC, pay special attention not to tamper with the anti-tamper switch. With twenty years of driving experience, I can tell you that the optimal position is the upper front of the windshield. First, thoroughly clean the area where the film will be applied to ensure it's free of dust and grease, then firmly press the adhesive on the back of the device. Avoid attempting to lift or move it. If the switch accidentally pops out, the entire device will lock and become unusable, requiring a trip to the ETC service center to unlock it—both troublesome and time-consuming. While driving, try to avoid bumpy roads and sudden braking to minimize vibrations that might loosen it. When washing or wiping the windshield, handle it gently and avoid poking the area with force. I've noticed many people trigger issues out of curiosity or improper installation, only to find out at the highway entrance that automatic payment isn't working, causing panic. It's better to install it properly from the start for hassle-free use.
As a newbie to ETC, I must remind everyone that the anti-tamper switch is quite prone to accidental triggering. During installation, find a reliable shop or properly secure it yourself - don't randomly press the button. While driving, avoid slapping or touching the device, especially when it's positioned near air vents. If accidentally triggered, visit an official service point immediately - forcing it may cause damage. I've learned much from online forums - a common beginner mistake is applying excessive force when cleaning the windshield, causing switch activation and malfunctions. Regularly check for device looseness - these small habits save significant time and toll fees while enhancing driving safety.
The ETC anti-tamper switch is actually a protective mechanism to prevent unauthorized removal of the device. To avoid accidental activation, proper installation is key: find a flat area on the windshield, adhere it firmly, and avoid moving it afterward. During use, prevent violent driving that may shake the device; when cleaning, gently wipe the surface without pressing the button area. If the switch pops out accidentally, only professional service points can reset it. Don't attempt DIY repairs as it may damage the device and violate regulations. Once properly installed and left undisturbed, you'll enjoy hassle-free automatic toll payment with minimal issues.
