Feature: High quality. Dynamically monitor: This motorcycle Tire Pressure Monitoring System is dynamically monitors all tire pressure and temperature, improves fuel efficiency, and prolongs tire life and ensures driver safety. Long battery life and keep safe: The Bluetooth-Compatible external Motorcycle TPMS sensors , with long lasting battery life for almost 3~5 Years. Easy operation via APP: This BT TPMS is support Bluetooth-Compatible 4.0 or above and APP Operate. Tire Pressure Monitoring System is designed for cellphones, support APP for iOS and Android. When do the BT scan, the APP will ask for permission of location, please allow to use it, it is android system request when we develop the Bluetooth-Compatible TPMS. High Accuracy: Real time monitor with 2 TPMS Sensors, waterproof and anti - corrosion, anti -theft technology, fully qualified for rainy days. High sensitivity, good accuracy for measuring pressure and temperature. Easy Setup: You can set up in 3 easy steps in just 10 minutes. 1. Remove tire valve caps, put in anti-theft screws;2. Install outer sensor on tire valve in order; 3. Hold the sensor, tighten anti-theft screw." Warning: Support cellphone with BT 4.0 or above. Do NOT support Cellphone with BT lower than 4.0.(Due to the different hardware performance of android phone manufacturers, data transmission may be delayed, which is a normal phenomenon). Product displays by cellphone. During driving, please be careful when viewing tire pressure and temperature in cellphone. If tire pressure accelerates down or up continuously,please stop car and check if there's any problem with the tire. This product can read tire pressure and temperature, but it cannot avoid sudden accident caused by tire. It's important to use tire with high quality. Slightly tire leakage makes tire pressure decreases over time is normal. It has nothing to do with this product installation. Outer Sensor Installation: Each sensor has a unique ID code. Please make sure sensor installed on corresponding tire valve. Note: When spin the sensor to tight, please open the APP in cellphone (Choose Auto Pair) and Press “Search” button at the same time to finish sensor bind shortly. Attention: Please follow the mark and install sensor on corresponding tire. Please save the installation tools (screws and wench) in car, for installing or un-stalling sensor. After sensor installation, please check if there's tire leakage.
