Recommended safety distances between
portable and mobile RF telecommunications devices and the protherm II
The protherm II is intended for use in an electro-magnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the protherm II can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the protherm II as recommended
below, according to the maximum output power of the communications equipment

For transmitters rated at a maximum output power not listed above the recommended
separation distance d in metres (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.
