Table 6:
Recommended separation distance between portable and mobile
RF communications equipment and the CS524 Qseal-auto
The CS524 Qseal-auto is intended for use in the electromagnetic environment in which radi-
ated RF disturbances are controlled. The customer or the user of the CS524 Qseal-auto can help
prevent electro-magnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the CS524 Qseal-auto as recom-
mended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separa-
tion 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 80MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is af-
fected by absorption and reflection from structures, objects and people.
