4. Electrical specification 4.1 Power supply specification Modem power(V_BATT) should be provided DC3.8V ± 0.1V, 2.0A. Modem power is provided according to inner function and per block using DC regulated circuit. It is controlled with each power depending on the mechanism to reduce power consumption to a minimum. PA is used directly V_BATT because of a lot of power input power source. Thus, It can be resulted in breakage of PA in excess of the rated input power.

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. Regardless of the power levels, care should be taken to minimize human contact during normal operation.
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. This module may not be co-located with any other transmitters or antennas.
