Packing List: 1pcs* Speed Detector 1pcs* Car Charger 1pcs* Non-slip Mat 1pcs* Instruction 1pcs* Packing Box Note 1: 1. V9 Automotive Speed Detector cannot detect traffic cameras, but it can only detect k and ka band. 2. At high speed, you can use normal mode, so your sensitivity will be higher. If there is a high-speed mode when you return to the urban road, the speedometer will reduce the anti-interference ability to protect the clutter. 3. The highway mode will reduce the interference from ordinary urban roads. 4. The urban mdel market is more sensitive and more susceptible to interference from microwaves or transmitters, so it can receive waves more and more sensitively. In this case, please slow down as soon as possible to reduce losses. Note 2: 1. Transition: 1cm = 10mm = 0.39 inch 2.
