Specifications: Condition: Brand New Type: Car Reverse Parking Kit Power Cable Length: approx. 0.8m LCD Display Cable Length: approx. 5m Sensor Cable Length: 2.3m per sensor (rear) /6.3m per sensor (front) Rated Operating Voltage: 12V DC (9.6 ~ 16V DC wide voltage operation) Working Current: 20 ~ 180mA Detection Distance: 30CM250CM Alarm Volume: 80dB Working Temperature: -40 ~ +80 Ultrasonic Frequency: 40kHz 1kHz Features: Car radar collision avoidance system is used for car exercises, berths and other safety aids. After the installation of four probe car, reversing, automatically start probing after obstacles. 4 probe installed in front of the car, when driving forward, when braking, start. 2.3Meter of cable comes with each probe censor. When the brakes, the front of the probe automatically work, loose brakes, the probe automatically delay about 10 seconds to stop working. Heartbeat step by step display function, numbers, sounds step by step tips. Microcomputer intelligent control, accurate figures show the distance between obstacles. Anti-electromagnetic interference, the electronic system without any impact. Probe with embedded installation, black-color configuration sensor compact, easy installation. Alarm prompt way: Voice prompts: The system uses three kinds of sound, mute, beep, English live voice mode switching between the three. The closer the obstacle, the more rapid. Light bar tips: the use of white color light bar, heart-based tips obstacle distance. Digital tips: in the middle of the display, the obvious number of tips obstacle distance, accurate and clear at a glance. Notice: Please pay attention to the following issues during the installation process: Wiring method: ABCD (rear sensor) EFGH (front sensor) Installation height is about 50cm. Do not press hard the middle of the sensors during installation. Keep the sensors wire away to a heat source (such as a smoke exhaust pipe or an engine compartment). The radar host has eight interfaces ABCDEFGH.And the host must be installed at the rear of the car like the picture shows. When reversing, sensors ABCDEH working.FG does not work.When braking forward. GEFH working. The monitor is not working when the vehicle is not in the state of braking and reversing The red line connect ACC power is not for working.It is for braking delay.The working lines are the yellow line connect Reversing light power and white line connect Braking light power.
