Recommended separation distance between portable and mobile

RF communications equipment and the ET2400LM

for all EQUIPMENT AND SYSTEMS that are not LIFE-SUPPORTING

Recommended separation distances between portable

and mobile RF communications equipment and the ET2400LM

The ET2400LM is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the ET2400LM can help prevent electromagnetic interference by maintain- ing a minimum distance between portable and mobile RF communications (equipment) and the ET2400LM as recommended below according to the maximum output power of the communications equipment.

	Separation distance according to frequency of transmitter
Rated maximum output	150 kHz to 80 MHz		80MHz to 800 MHz		800 MHz to 2.5 GHz
power of transmitter
W	d=1.2		d=1.2		d=2.3
		P		P		P
0.01	0.12		0.12		0.23
0.1	0.37		0.37		0.74
1	1.2		1.2		2.3
10	3.7		3.7		7.4
100	12		12		23

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.
