Omron HBP-1300 instruction manual Separation distance according to frequency of transmitter

Recommended Separation Distances:

Recommended separation distance between portable and mobile RF communications equipment and the HBP-1300

The HBP-1300 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the HBP-1300 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the HBP-1300 as recommended below, according to the maximum output power of the communications equipment.

	d = 1.2	P	d = 1.2	P	d = 2.3	P
0.01	0.12		0.12		0.23
0.1	0.38		0.38		0.73
1	1.2		1.2		2.3
10	3.8		3.8		7.3
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 determined 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.

Note1: At 80MHz and 800MHz, the separation distance for the higher frequency range applies

Note2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
