4. Electrical Specifications 4.1. Power Supply Specification Modem power(V_BATT) should be provided DC3.8V ± 0.1V, 1.5A. 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. In addition, surge and ESD should be designed to block the influx in order to prevent damage to the modem. Pin NO. Signal Name Function (Modem) MIN TYP MAX 31,32 V_BATT I 3.7V 3.8V 3.9V 4.2.

11. 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. This module should be used more than 20cm(8 inches) from the body when wireless devices are on and transmitting. This transmitter must not be collocated or operate in conjunction with any other antenna or transmitter. Operation is subject to the following two conditions: (1) this module may not cause interference , (2) this module must accept any interference that may cause undesired operation. 11.1 Information for integrator The integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the user manual of the end product. The user manual which is provided by integrators for end users must include the following information in a prominent location. To comply with FCC RF exposure compliance requirements, the antenna(W8E-MWC-20 Tri-band Dipole Antenna) used for this transmitter must be installed to provide a separation distance of at least 20cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Label for end product must include Contains FCC ID : YZP-D660V or A RF transmitter inside, FCC ID : YZP-D660V
