K-FTH-1012 Instructions for Use
Recommended separation distance between portable and mobile RF communications
equipment and the Test Tube Heater
The Test Tube Heater is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Test Tube Heater can help prevent
1
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Test Tube Heater 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
