Note: To test the PCB on its own without a housing or SIM card the unit must first be put into test mode and then into Tx or Rx mode using the applicable manual test commands. Ensure that a battery is installed during this, since the battery acts as a SIM card presence detect for the unit. The PCB can then be taken out of the housing for any analysis.
