Recommended safety distance between portable and mobile RF telecommunication devices and
the HICO-Variotherm 550
The HICO-Variotherm 550 is designed for operation in an electromagnetic environment, in which the RF
disturbances are controlled. The customer or the user of the HICO-Variotherm 550 can help to
prevent electromagnetic disturbances by keeping a minimum distance between portable and mobile RF
Telecommunication devices (transmitter) and the HICO-Variotherm 550 depending on the power output of the
communication device, as indicated below.

For transmitters whose maximum output power rating is not listed in the table above, the distance
can be determined by calculating the equation on each column, 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 the frequency range applies.
NOTE 2: These guidelines may not apply in all situations. The propagation of electromagnetic waves is affected by
the absorption and reflection from structures, objects and people.
