NOTE: Ut is the a.c. mains voltage prior to application of the test level.
Portable and mobile RF communications equipment should be no closer to any part of the
3600 Handpieces, including cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.
