If the maximum output of the transmitter is not shown in the above table, use the formula to
derive the recommended safety distance d (Meter) with P (Watt) being the maximum output
of the transmitter.
Attention: For frequencies between 80 MHz and 800 MHz, use the higher frequency range.
Attention: These guidelines may not be applicable to all situations. Electromagnetic waves
can be absorbed or reflected by buildings, objects and people.
