February 2013 1 CBSTPSEN01 User manual V1.3 CBTPSEN01 User Manual This device complies with part 15 of the FCC Rules and with Industry Canada license‐exempt RSS standard(s). 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. Application Notes: The installation of the product must be reduced to a minimum while ensuring 24/7 operation over the life of the tire. SST wireless rim sensor is packaged to provide efficient user friendly installation and designed to overcome all the environmental challenges presented. The wireless rim sensor while incorporating the latest in technology is formed into a simple low profile package that is attached or secured to the rim offering maximum validity and integrity of data captured and processed. The low profile of the package along with the positioning of the sensor allows for the use of standard tire install procedures and equipment. Product Description: An “interactive” wireless sensor that attaches to the wheel rim (nylon strap), to measure the contained air temperature and pressure in real time.
