a Field strength from fixed transmitters such as base stations for radio (cellular/cordless) telepho-
nes and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot
theoretically be predicted with accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the field strength measured at
the location where the SafeSense
the product should be monitored to verify that it is functioning as intended. If unusual performance
is observed, additional steps may be required such as a change in orientation or a different location
for the system.
b For frequencies between 150 kHz and 80 MHz, the field strength should be lower than 3 V/m.

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 of the transmitter in watts (W) according to the
manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies

Electromagnetic propagation is affected by absorption and reflection from structures, objects
and people.
