800M… I'm not sure about this, but it seems like it uses a circuit designed for 800M GFSK data transmission, along with other circuits. Because, according to the regulations, this frequency is definitely non-compliant... However, there's one thing: what is the intended use of this device? ICU (it's likely used in ICUs as well) I remember that the standards for operating rooms are similar to those for ICUs. And the walls are also lined with lead plates? So, it shouldn't cause much interference either?
