Oro Technology Co., LTD Tire Pressure Monitoring System MODEL : W410-A ORO TPMS User Manual To ensure correct operations and services please read these instructions before installing and operating the TPMS FCC Notices 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. 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. CAUTION: Any changes or modifications not expressly approved by the grantee of this device could void the user's authority to operate the equipment. RF exposure warning: The equipment complies with FCC RF exposure limits set forth for an uncontrolled environment. The equipment must not be co-located or operating in conjunction with any other antenna or transmitter. This equipment should be installed and operated with a minimum distance of 20cm between the radiator &your body. W410 Tire Pressure Monitoring System ORO-W410 Tire Pressure Monitoring Systems (TPMS), can monitor and provide tire pressure, tire temperature, and car battery information in real time. This real time information can extend tire life, reduce fuel consumption, help monitor battery status, and provide a more safe driving condition. ORO-W410 Tire Pressure Monitoring System includes 4 tire sensors, and1 receiver display. The TPMS monitors the pressure/temperature by snap-in installation into the wheel, and transmits the tire information wirelessly to the receiver. The TPMS display will trigger an alarm when any abnormalities happen to the tire in order to prevent any possible accidents that may happen to the driver/vehicle. W410 TPMS Specification 1.Transmitter Specification Battery Life Up to 5~ 7 years in normal use Power Supply 3V Lithium battery Operating Humidity Max 95% Storage Temperature -40 °C to 125 °C Operation Temperature -40 °C to 115 °C RF Strength 0.0463 mW Operating Frequency 433.92 MHz Pressure Monitoring Range 0 ~ 116 psi (or 0~800 kPa or 0~8 bar) Pressure Reading Accuracy ±1 psi (or ±7 kPa ; ± 0.1 bar) Temperature Monitoring Range -30 °C to 115 °C Temperature Reading Accuracy ±3 °C Module Weight 22.7g ± 1g 2.

The display will be brighter in the day and darker in the night to ensure that the user will be able to read the LED Display clearly and not be affected by external lighting. 2. Operation to Change Display Mode W410 has 3 different modes. They are Tire Pressure Display Mode, Temperature Display Mode, and Pressure-Temperature Alternate Mode. The display will show the tire pressure mode once it is turned on. To enter the temperature mode press the MODE button once and to display pressure-temperature press it another time. The system will continuously monitor the tire pressure, tire temperature, battery voltage, no matter what kind of information is being displayed and will notify the driver whenever anything abnormal happens. If the user does not change from the factory default, the system will show the tire pressure display. The 3 modes of display are as follows: a.Pressure Display Mode: Display of 4 tires pressure and battery voltage unit only. b.Temperature Display Mode: Display of 4 tires temperature and battery voltage unit only. c.Pressure-Temperature Alternate Display Mode: Rotating display of tire pressure and temperature with a constant display of battery voltage. 3. How to Change the Unit of Tire Pressure and Temperature W410 displays 3 kinds of pressure units, bar, kPa and psi. For temperature, Celsius or Fahrenheit can be displayed. To change the factory default for pressure or temperature, press the MODE button for 3 sec. 4. How to Modify Factory Default W410 has 4 factory default modes for users to choose from. Press the SET button continuously for 3 sec. to enter the set up mode from Front Tire-Standard tire pressure set up, Rear Tire-Standard tire pressure set up, Tire Temperature-Over Temperature Warning, and Operation Mode. For other parameter settings, please refer below for the relevant process: NOTE: The user should change the suitable pressure unit for own vehicle before entering into the setup mode. Set up Front Tire Pressure Value: Range 24psi~80psi (1.7bar~5.5bar), the default …
