SIM345 EVB User Guide 6 Illustration 6.1 Running (1) Connect the SIM345 module to the 60 pins connector on SIM345 EVB, inserting 5V direct current source adapter, switching the S103 switch on off state, S202 switch on ON state; (2) Press the ON/OFF for about 2 second, and then SIM345 module begins running. You can see the light on the EVB flashing at a certain frequency. By the state, you can judge whether the EVB and SIM345 can run or not.
●RF exposure requirements To allow compliance with RF exposure requirements，the SIM345’s maximum output power is 33dBm in GSM850/GSM900 band，or 30dBm in DCS1800/PCS1900 band， and the maximum antenna gain is 3dBi，and the minimum cable loss is 0.5db. ●The Antenna Parameter of SIM345 VSWR(Max.)Operation GSM850/GSM900 DCS1800/PCS1900 ≤2.5 ≤2.5 ≥3 ≥3 >0dBi > 1dBi >30dBm >27dBm band VSWR(Min.
