1 group
M4-HD bladder scanner uses RF energy only
for its internal functions. Therefore, its RF
emission frequency is very low and it is
almost impossible to cause interference to
nearby electronic equipment.
RF emission GB 4824
Class B
M4-HD bladder scanner is suitable for use in
all facilities, including domestic and
residential public low-voltage supply network
directly connected to households.
