Recommended Safe Distances between
Portable and Mobile RF Communications Equip-
ment and the CardioMessenger
These guidelines may not be applicable in all cases. The
spread of electromagnetic waves is influenced by absorp-
tion and reflection from buildings, objects, and humans.
Note: The higher frequency range applies at 80 MHz and
at 800 MHz.

For transmitters whose maximum nominal output is not
indicated in the above table, the distance can be calcu-
lated using the equation in the respective column, where
P is the maximum nominal output of the transmitter in
Watts (W) according to the transmitter's manufacturer.
