2A3UN-TPMSTPMS Tire Sensor

SensorUserManual 一、Sensorinstallationmethod(usuallyrequiresinstallationat a repair shopor 4S store) 1、Deflatethe tires 2、Usea toolto removethe tire nozzleend,and theninstallthe sensorin the followingdirectionto the nozzlehole position. 3、Finallyreturnthe tire to its originalpositionand fully inflateit. 二、Sensormatchingmethod 1、If the sensoris equippedwithautomaticmatchingfunctionand the current vehiclemodelalso supportsautomaticmatchingfunction,the automaticmatching methodcan be used:the car is turnedoff for 20 minutes,and thenthe car is started to driveat a constantspeedof 60 km/hfor 20-30minutes.If the automaticmatching is successful,the tire pressuredataon the tire pressureinterfaceof the car dashboardwill be automaticallydisplayed. 2、If the sensordoesnot haveautomaticmatchingfunctionor the currentvehicle modeldoesnot supportautomaticmatchingfunction,it is necessaryto contactthe staff at the 4S storeor repairshopfor sensormatching. Sensor conducts wireless communication via 433.92 MHz. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment The device can be used in portable exposure condition without restriction.
