Hello,

We have multiple DT80M datalogger over the country and for some reason, they many of them have started to lost the SIM pin code. This affects only for this settings, all others ones are fine. It happens randomly, between month or like once in a year. After entering the SIM Pin again, everythings works like excepted. This phenomen was not going on a couple of years ago with these loggers.

Hi ixus,

It is impossible to lose the logger's internal setting unless when you found it the logger was in a "safe mode" which revert all settings to the default. The safe mode itself is achievable through triple push.

Unfortunately, this triple push can have two methods, it is not only by pressing the switch from the small hole next to the Ethernet port but also by sequencing the power between on and off.

In our opinion, the power sequencing is the cause of your logger entering the safe mode.

Notes:
Even with the lose of the clock battery, the logger's internal setting remains.

Best regards,
