Hi @FrTmu,

We don’t recommend opening the unit as it will void its IP67 protection and can lead to further issues. Can you send a description of your issue to We will look into it.

Hi Alesia,
i understand about IP67, but i have two emild that are not in worhing well, (RS2 and RS2+) i just want to see what append. Il is not a problen if after the two RS will be full dead.
Let me know which key to use.


I do not know what the RS2/+/3 size is, but the old RS uses 6 point T10 TORX.

Get yourself a multi sized tool to try.

Either way, see if Emlid will help before opening it and if not… well, go from there!


I answer to mylself and confirm:
To unscrew and open RS2 and RS2+ you need à 6 point T10 TORX 40 mm long minimum

Thank you for the update.
