How it works: Hidden Shield automotive electronic lock is adopting international advanced RF transmission technology, when the recognizer in the open state, the second automatically send a different set of signals (1,200,000,000 group password), distance of 5 meters, when the engine is started, the host system begins scanning your password (this time the vehicle can be started normally), the host scanned into the correct password to open the vehicle can continue to go, if the scan fails within 20 seconds will automatically shut off the engine. Precautions This product is used in the automotive 12v power; initial use open recognizer (factory closed), press the function key identifier side indicator flashes once to; carry recognizer while driving, try to avoid car key together; vehicle is started, the system host scan signal successfully, the host issued a "tick" sound to indicate legally drive, start the car within 20 seconds if the signal fails scan automatically turn off; if a long time when not in use, turn off the switch identification to extend battery life recognizer by identifying the side function button for 3 seconds, the light flashes twice to close the recognizer; identifier lost or damaged if the need to temporarily start the vehicle, the emergency switch on the host "Emergency "position. Replace the battery recognizer recognizer using high-capacity battery CR2450 button batteries, can use more than two years under normal circumstances, if capacity is less than the operating voltage, each time you start the vehicle when the host will issue a "beep, beep, beep" rapid response 10 seconds and identify the LED light will flash often prompts owners in a short time you can replace the same type of battery. Identifier and host identifier missing pair if need to re-match, press the host learning key, and then press the function key identifier on the side of the host "tick" sound that is a match (Note: currently used recognizer also need to re-match ). A host can only match two identifiers, thus missing the identification code reader also will fail. System parameters Host Operating voltage: 12v, host current: engine starts 5mA; flameout 0mA recognizer Voltage: 3v recognizer Power: 5uA signal transmission distance: 5 meters Host Size: 65mm * 40mm * 23mm Special note: If the owner Close identification or forget to bring recognizer to start the vehicle, the host Less than 20 seconds internal scan password Compulsory vehicle does not start properly locked, lifting methods: At this point simply click on the function key identifier; owners of long-term use of the identifier should be kept open to avoid the owner to start the vehicle, the host can not be scanned into the password Compulsory flameout, causing inconvenience to you; host installation of this product should be avoided metal inductive antenna is completely blocked; This product is not waterproof design, the host should be avoided installed in a position that can be immersed in water.
