PMN: Doran TPMS Sensor for OTR  User manual 5. Sensor Installation Instructions 5.1 Program the sensor ID into the receiver To make TPMS products work properly, the sensor ID must be programmed into the receiver for each wheel to be monitored. The following operations are performed on the receiver. a) Press the P button to enter the program mode. Select the wheel position and press S button to enter the sensor ID. b) Input the last three digits of the sensor ID into the receiver by navigating the arrow keys. c) Press the S button for three seconds to confirm the information. If there are more wheels to be programmed, repeat steps a-c in above until all the wheels have the sensor ID entered. Finish the programming process by pressing the P button for 5 seconds to quit the program mode. 5.2 Install the sensor onto the valve stem Once the receiver is prepared and programmed, simply screw the sensor onto the valve stem in each wheel. Be sure to inspect and replace any defective or cracked valve stems before installing the sensors. If replacements are necessary, suggest replacing the valve stems with a Brass or Stainless-Steel stem. It does improve the life of the stem due to premature failure from drying out and cracking. Inferior stems have been found in the market and can cause extensive damage. The sensor should he tightened only by hand not with a tool. Use a firm grip and tighten the sensor. When the sensor seal makes contact with the end of the valve stem only tighten the sensor an additional 1/2 turn. This should be tight enough to seal the sensor and hold it in place. Check for leaks with a soapy solution. The monitor or receiver will begin to receive and recognize the sensors, and it will display the wheel positions as they are received on the screen. 6.
