spirobank G User Manual cod. 980026 Rev 2.0 Page 46 of 46
Recommended separation distances between
portable and mobile RF communications equipment and the spirobank G
The spirobank G is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the spirobank G can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the spirobank G 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.
