The ETC installation position for small cars is generally in the upper middle part of the front windshield, while for large vehicles like trucks and buses, it should be installed in the lower middle section. The appropriate installation height should be no less than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect microwave communication signal transmission, ETC should be installed in the microwave sunroof strip area. ETC stands for Electronic-Toll-Collection system. To apply for ETC, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If applying by a proxy, the agent's valid ID card is also required. The photocopy of the registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card under the owner's name (aged 18-60) is needed for deducting highway tolls. Here are important considerations for ETC installation: 1. Avoid obstructing the driver's view - The best position is behind the rearview mirror: Many car models have steeply angled windshields that already reduce visibility. Installing ETC without considering this may increase blind spots. The right side behind the interior rearview mirror is ideal as it minimizes view obstruction. 2. Ensure proper charging: ETC devices require power but generally don't need manual charging or battery replacement as they feature built-in solar panels. Avoid installing on windshield's blackout areas or positions that might block sunlight to the solar panel. 3. Never remove the device after installation: The adhesive contains an anti-tamper mechanism. The device will lock if removed (triggered by a spring-loaded switch) and requires professional reactivation at ETC service centers. This prevents multiple vehicles sharing one device. ETC usage notes: The effective transaction range is 8 meters. Maintain at least 10 meters distance from preceding vehicles to avoid accidental toll payments for others. ETC lanes have a maximum recognition speed of 20 km/h - excessive speed causes read failures. Insufficient balance in debit card-linked ETC accounts will also lead to payment failures.
