A robust product

The device is equipped with an auto-test system which

is launched when the device is switched on. This test

ensures that the EME Guard is functioning normally and

that battery level is sufﬁ cient. In any case, if the battery

level is too low, an orange warning light alerts the user

immediately.

The case is metallic and ensures an IP55 Ingress

Protection level, ideal for outdoor use.
