zSpecification:
*Specification is subject to change for product performance without any notice
B. Installation:(Always have the display power on before installation of sensors)
Label on Sensor
1. Labeled with FL: Front Left Wheel.
2. Labeled with FR.: Front Right Wheel.
3. Labeled with RL.: Rear Left Wheel.
4. Labeled with RR.: Rear Right Wheel.
Installation of Sensor:
SUGGESTION: With the display power on, the
communication of sensor & display will run well prior to the installation of sensor。
1. Make sure the top part and bottom house of the sensor are tightened
(Applied with enclosed wrench)
2. Remove original valve cap from stem
3. Screw-on the enclosed Hex nut on the valve; then, mount the valve
sensor onto the valve stem. Make sure the Hex nut is being tighten in reverse
clockwise direction to affix with the bottom part of the Valve Sensors。
NOTICE: To Check the valve if it is leaking after installation
,it can be confirmed from the display to see if the
pressure has dropped down.
