Compliance Electromagnetic environment - guidance
Group 1 /Class B The Welch Allyn Masted Scale uses RF energy only for its internal
function. Therefore, its RF emissions are very low and are not likely to
cause any interference in nearby electronic equipment.
Class B
The Welch Allyn Masted Scale is suitable for use in all establishments
other than domestic and those directly connected to the public low-
voltage power supply network that supplies buildings used for domestic
purposes.
