9. RFx Information The RF field strength of the wireless module or modules that may be embedded in your TCU is well all international RF exposure limits as known at this time. Because the wireless modules(which may be embedded into your TCU) emit less energy than is allowed in radio frequency safety standards and recommendations, manufacturer believes these modules are safe for use.
10. FCC Approval This Module complies with parts 22, 24, 27 of the FCC rules. This device complies with FCC radiation exposure limits set forth for an uncontrolled environment. This module should be installed and operated with minimum distance 20cm between the radiating element of this device and the user.
