16�3�1 General Information about GPRS Devices
We recommend checking and cleaning SIM cards once a year.
The contact points of the SIM card could start corroding due to humidity and should
be cleaned regularly with a suitable medium (no screwdriver or cleaning solvents) to ensure trouble-free
operations.
Caution
Only remove the SIM card after the Solar-Log™ has been turned off. Removing the SIM
card during normal operation may cause a card defect.
Corrosion on the SIM card contact points is an indication that the installation location does conform to the
IP20 protection class.
