What are the methods to determine if the ETC status is normal?

To determine if the ETC status is normal, follow these steps: 1. Press and hold the anti-tamper switch on the back of the OBU device. The red light will flash once, and then the ETC electronic tag's screen will display "Tag Invalid" or "Please Insert Card." 2. Insert the ETC card into the ETC electronic tag. The driver will immediately hear a "beep" sound, and then the ETC electronic tag's screen will display "Debit Card" or "Amount." At this point, it indicates that the ETC device is in normal status.
As an ordinary car owner, I always take a quick glance at the small green light on my ETC device every time I get in the car. If it's emitting a steady green light, there's usually no problem. Before my last long-distance trip, I noticed the light wasn't on. I simply pulled out the card, wiped the metal contacts, and reinserted it, which fixed the issue. When passing through the toll station, hearing a beep and seeing my license plate and the toll amount displayed confirmed everything was working normally. If the device doesn't respond, I first try switching to another lane. Sometimes, if the battery is low, the device flashes a red light, which means it's time to visit a service point for a battery replacement. For those who don't drive often, it's a good practice to take the car out monthly and pass through an ETC lane to test the device.
