semaphore:
What is the two squares and house symbols mean? They are on the wall adapter.

Mechatrommer:
maybe the house means use indoor.

GeoffS:
The two concentric squares indicated that the device is doubly insulated to Class II and should not have an earth connection
Can't say I've ever seen the house symbol.
