4. Electrical specifications 4.1 Power supply specifications The host system provides the power supply (V_BATT)DC 4 V, 2.5 A to the device. The internal power supply module manages the power supplied to the integral circuits and maintains constant voltages. This module also controls each power block to minimize power consumption. In particular, the PAM (power amplifier module) consumes a lot of power, so it receives a direct power supply of 4 V from the V_BATT.

8. RFx information The strength of the RF field produced by the wireless module or modules embedded in the TCU is well within all international RF exposure limits known at this time. Because the wireless modules embedded in the TCU emit less than the maximum amount of energy permitted in radio frequency safety standards and recommendations, the manufacturer believes these modules are safe for use. Regardless of the power levels, care should be taken to minimize human contact during normal operation.
9. Approbation FCC This module complies with FCC/IC rules. FCC : Part 22, Part 24, Part 27 IC : RSS-130, RSS-132, RSS-133, RSS-139 Furthermore, this device complies with FCC/IC radiation exposure limits set forth for uncontrolled environments. This module must be installed and operated with minimum distance of 20 cm between the radiating element and the user.
