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 higher frequency range applies.
Note 2 These guidelines may not apply to all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.

Electromagnetic environment - guidance
The Sera TM 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.
The Sera is suitable for use in all commercial,
