Usage methods after successful ETC activation: 1. The ETC transaction sensing range is 8 meters. When encountering a stationary vehicle ahead, maintain a distance of over 10 meters to prevent automatic fee deduction for the preceding vehicle in case its ETC device malfunctions or is absent; 2. The recognized speed limit in ETC lanes is 20 km/h - excessive speed will prevent vehicle device information from being read, resulting in failed payment; 3. Unauthorized removal/relocation of OBU devices, or detached/loosened ETC electronic tags will deactivate the tag. These can be inspected at the issuing bank or highway service center. Non-deliberate detachment only requires reactivation.

After successful activation, the device will automatically operate, but proper operation is required for smooth usage. First, ensure the card is securely inserted in the device without tilting. When driving on the highway, specifically choose lanes marked with ETC, maintaining a speed of around 30 km/h—too fast and the device might fail to scan. Don’t hesitate when passing through the toll station; the system deducts the fee instantly, and records can be checked on the mobile app or linked account. When I first started using it, I always worried about insufficient balance, so I topped up the app in advance. Also, on bad weather days like heavy rain or fog, the signal might be weak, so I avoid ETC lanes and use manual lanes for safety. Regularly check if the adhesive securing the device to the windshield has aged, and reinforce it if loose. Avoid parking in direct sunlight to prevent overheating and malfunctions. Once you get used to it, it saves time and money—much more convenient than cash queues, especially on long drives.

I've been using ETC for several years, and it's been a breeze since activation. Just head straight for the ETC lane on the highway, keep your speed under 40 km/h, and you'll zip right through. The system automatically deducts the toll—just install an app on your phone to check your balance and transaction history, so you don’t panic when it’s suspended due to insufficient balance. I make it a habit to top up my account with 100 yuan at the start of each month to stay on the safe side. When passing through toll stations, avoid tailgating; keep some distance to ensure accurate scanning. Newcomers shouldn’t stress—just practice a few times to get the hang of it. If the device acts up occasionally, like the light not turning on, I’ll try restarting the engine or giving the device a gentle tap. The best part? You get a discount on toll fees, saving both money and time, making long trips much smoother.

After activation, once you turn the key in the car, the device goes into standby mode. Just aim for the ETC-only lane on the highway, slow down a bit, and pass through. The system's sensors automatically read the card and deduct the fee—you just focus on driving. Keep an eye on your account balance in the app and top up when it's low. I've used it in rainy weather; if the signal is unstable, switch to a manual lane temporarily. Make sure the device is securely fixed to avoid shaking, which can affect signal reception. Overall, it's foolproof, hassle-free, and efficient.
