Introduction
The purpose of this application note is to explain how to correctly insert the SIM card into the Argon 100 GSM remote
temperature monitor, and to debug the network connection if the product doesn’t work as expected.
SIM Insertion Method
Remove all power to the Argon 100 by unplugging the power supply. Although the unit has been designed so that no
damage should occur if the SIM card is plugged into a powered unit, it is good practice to insert the SIM card without power
applied to prevent any possibility of damage.
Line up the SIM card and the Argon 100 as shown in Figure 1. Note that the SIM card is polarized and the correct orientation
is determined by the position of the cut corner of the SIM card.
