For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be estimated using the equation applicable
to the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.

DPA technology for a more accurate measurement

The smartLAB
measuring technology called DPDA
(double pulse detection algorithm)
with which the units manage the
blood pressure signals twice. The chart
left shows the blood pressure signals
after managed by DPDA. The result is a
more linearized curve, proving the improved measuring accuracy of your
