Richmar HydraTherm - Recommended Separation Distances for RF Equipment

APPENDIX A - EMC TABLES
RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND
MOBILE RF COMMUNICATIONS EQUIPMENT AND THE HYDRATHERM
COMPOSITE HEATING UNIT
The HydraTherm Composite Heating Unit is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the
user of the HydraTherm Composite Heating Unit can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the HydraTherm Composite Heating
Unit 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 meters (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
aected by absorption and reflection from structures, objects and people.
