To all customers,
Thank you for your support.
As we received plenty of repeated questions from you, we decided to create this thread to post answers here. This thread will keep updating to help you solve your problems.
Here are the questions and answers:
1. Where can I purchase sensors seperately?
Currently I am afraid that there is no such sensors sold seperately as you described. You can contact your seller to ask for aftersales service.
1. How to connect the 70mai TPMS Lite to a mobile phone?
Download the “70mai” app. Make sure that the receiver is turned on and Bluetooth is turned on for the mobile phone. Open the app and follow the on-screen instructions to connect.
1. What happens when the tire pressure is wrong?
Insufficient tire pressure: The tire will be damaged and may puncture at high speed. If the tire pressure is too low, the wheel hub will be susceptible to damage.
Excessive tire pressure: The tire will be bumpy and will not have sufficient grip. The tire will be susceptible to damage and may puncture easily.
2. Why the receiver can receive data sometimes, but not at other times?
Check if the receiver is too close to a source of interference, whether the sensor transmitter is damaged and whether the sensor has run out of battery.
3. How to determine what is the correct pressure for the tires?
The car manufacturer will provide reference tire pressure values. As the weight distribution and tire specification for each car model is different, the recommended tire pressure for the front wheels and back wheels, and at no load and full load would be different. Users can find such information on the car door of the driver’s seat (near pillar B), inside the fuel tank cover or in the car manual.
4. What is the recommended tire pressure?
Based on the principle of expansion and contraction under different weather conditions, during winter, the tire pressure should be increased by 0.1-0.2 bar over the standard tire pressure (as recommended by the car manufacturer); while in summer, the tire pressure should be reduced by 0.1-0.2 bar.
5. Why does the display of the 70mai TPMS Lite receiver show “–“?
The sensors may still be in sleep mode. Observe the display again after driving the car for a certain period of time.
1. Can users install the 70mai TPMS Lite on their own?
Yes, users can install the receiver and the sensors on their own.
Install the receiver: remove the film on the adhesive and attach the receiver in the direct view of the driver.
Installing the Sensor: first, install the hex nuts into the valves of the tires. Install the sensors on the tire nozzles according to the top marking. Tighten the sensors clockwise onto the tire valves. Use a wrench to tighten the hex nuts counterclockwise to the sensors to activate the anti-theft mechanism.
2. How long can the battery of a 70mai TPMS Lite sensor last? Can users replace the battery on their own?
The service life of the battery is about 2 years (based on 2 hours of driving per day). Users can replace the battery on their own. Use battery removal clamps to turn the sensor housing counterclockwise. Replace the battery with a new lithium battery with the positive (+) side facing up. Check the waterproof rubber ring is intact. Use battery removal clamps to tighten the sensor housing clockwise.
3. Is the display clear under strong direct sunlight?
The display of the 70mai TPMS Lite is made of an industrial-grade LCD screen with a wide range of working temperature. The screen can work normally within -20℃ to 70℃. With a high contrast and wide viewing angle, the special design of the display ensures that the reading can be seen clearly even under strong direct sunlight.
4. Are the sensors susceptible to damage?
The 70mai TPMS Lite uses automotive-grade sensors that have been tested under rigorous conditions to ensure that they are extremely difficult to be damaged due to normal use.
5. Will the receiver of the 70mai TPMS Lite drain the car battery? Is it necessary to turn off the system or unplug the charger after turning off the engine?
No, the 70mai TPMS Lite is powered by an in-car charger and solar panel. For most car models, power to the cigarette lighter receptacle is cut off when the engine is turned off. In addition, the receiver of the 70mai TPMS Lite will also enter sleep mode when the engine is turned off, so it will not drain the car battery. However, users can choose to unplug the charger as well.
6. Is the physical location (front left, back left, front right, back right) of the 70mai TPMS Lite sensors important?
Every 70mai TPMS Lite sensor as a unique ID number. By default, the sensors are already paired with the receiver. To ensure that the correct data is shown for each tire, users should install the sensors at the locations indicated.
7. If a sensor is installed to the wrong tire, must it be removed and re-installed?
No, just use the sensor binding function on the mobile app to align the sensors.
8. Can the tire pressure and temperature alarm settings of the 70mai TPMS Lite be changed?
Yes. By default, the tire pressure and temperature alarm settings for different car models are already set, so users do not need to input the values on their own. If your car model is not listed or you would like to adjust the settings, you can do so using the mobile app.
9. Can the 70mai TPMS Lite monitor the tires while the vehicle is stationary?
Yes. The 70mai TPMS Lite is activated by pressure changes. When the change in tire pressure exceeds 10kpa, i.e. 0.01 bar, the sensors will be activated. However, the receiver must be turned on in order to receive the data and activate the alarm.
10. Will there be any signal losses with the 70mai TPMS Lite when the car is moving?
No, 70mai TPMS Lite uses automotive-grade sensors that have been rigorously tested at high speeds to ensure there is no signal loss even when the car is moving at 200km/h.
11. Why does the tire pressure change significantly when the car is moving?
Generally, the tire pressure and temperature would be lower when the car is stationary compared to when it is moving. After moving for a certain period of time, the tire temperature should increase and tire pressure should increase by 0.1-0.3 bar. This is normal.
12. Why can’t the display be turned on after installation?
It is recommended to connect the receiver to the cigarette lighter receptacle of the car and let it charge for a while before turning it on for the first time.
13. What happens if the battery life of the receiver is not long enough?
The receiver uses an ultra-high definition color screen which requires a lot of power. Therefore, the battery life may not be sufficient for prolonged use. If the receiver cannot be charged through the solar panel, it can be connected to a power bank using a USB cable.
14. Sometimes, an alarm will be shown on the 70mai TPMS Lite, but no leakage is found. What is the cause of this?
It is possible that the tire pressure was higher before, but when the tire leaks, the pressure remains within the normal range. It is recommended to check for any foreign object that may be stuck on the tire.
