- Page 2 Remove the SIM cover located on top of the A3LA-I Iridium modem by unscrewing two hex bolts. Integrated SIM Chip Reader SIM Cover Under the SIM cover is an integrated SIM Chip Reader. The modem uses and requires an Iridium SIM chip for operation.
- Page 3 Connect an external antenna to the Iridium modem. Any of the four types of antennas offered by NAL Research is appropriate. Make sure the antenna has full view of the sky and the cable loss between the modem and antenna is less than 3 dB.
- Page 4 Wait for about 15 seconds for the modem to register with the Iridium satellite network. The A3LA-I is basically a “black box” with no indicators of any kind (power on light, satellite registration status, satellite signal strength, etc.). This can pose great difficulties to first-time users who are not familiar satellite modems.
