When removing the old ETC, you can use a hairdryer to heat the double-sided adhesive on the back of the ETC, then use a small plastic scraper to peel off the adhesive, and finally wipe it clean with a cloth. ETC Usage Notes: The ETC transaction sensing range is 8 meters. When encountering a vehicle in front that stops, to prevent the front vehicle's ETC device from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the front vehicle to avoid automatic sensing and paying for the front vehicle. The ETC lane recognition speed is 20km/h. If the vehicle speed is too fast, the vehicle device information cannot be read, which will also result in a failed fee deduction. Unauthorized removal or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to become invalid. It can be sent to the bank where the ETC card was issued or the highway service office for inspection. If the loosening or detachment is not due to human factors, it only needs to be reactivated. When using a debit card bound to ETC, insufficient balance will also result in a failed fee deduction. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card payment. Poor sensing due to excessively thick car windshield. Especially for vehicles that have undergone accident repairs with replaced windshields or those who have modified the front windshield need to pay attention.

Removing the old ETC device is quite simple based on my years of driving experience. Generally, the ETC is stuck to the windshield with adhesive. Find the edge of the device, gently pry open a small gap with your hand, then slowly push in with a plastic card or credit card to avoid scratching the glass with metal tools. If the adhesive is strong, you can apply a bit of alcohol or a specialized adhesive remover to soften it before peeling it off. After removal, clean any residual adhesive marks with a damp cloth. Don’t forget to contact your ETC service provider to deactivate the account to avoid accidental charges. Once these steps are completed, the windshield will be clean, making it easier to install a new device. The whole process requires patience—don’t rush it.

Removing an old ETC device requires careful operation. I recommend first wrapping the edges of the device with a cloth and gently prying it up. Most ETC devices are adhesive-mounted, so spraying some alcohol on the adhesive and waiting a few minutes for it to soften before steadily peeling it off is advisable. Avoid using excessive force to prevent glass damage. Ensure the device's power is disconnected during removal, and if it has a battery, remove it. After removal, contact the ETC company to cancel or transfer the service. No special tools are needed—a plastic scraper or credit card will suffice. For cleaning the glass, I use car cleaner, which makes it shine with just a simple wipe. The entire removal process takes at most ten minutes, with safety being the top priority to avoid any scratches.

When removing the old ETC device, first turn off the power, then slowly peel it off from the corner by hand. Use an alcohol swab to soften the adhesive for easier removal. After taking it off, clean the glass and deactivate the ETC card. The whole process is simple and quick.

Removing old ETC devices requires caution as damaging the windshield can be troublesome. When removing, I first use a warm air blower to soften the adhesive before taking off the device. Use plastic sheets as tools to assist, avoiding forceful pulling. After removal, promptly contact the service provider to deactivate it to prevent erroneous charges. Use neutral cleaners to remove residual adhesive from the glass. The entire process should be done smoothly, and avoid operating on extremely hot days.
