Lifeline Systems Inc. 7100MHB Manual De Usuario

Table 6 - Recommended Separations Distances between 
Portable and Mobile RF Communications equipment and 
GoSafe Lite
The GoSafe Lite 7150MHB is intended for use in the electromagnetic 
environment in which radiated disturbances are controlled. The customer 
or user of the GoSafe Lite 7150MHB can help prevent electromagnetic 
interference by maintaining a minimum distance between portable and 
mobile RF Communication Equipment and GoSafe Lite 7150MHB 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 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.

 At 80 MHz and 800 MHz, the separation distance for the 

higher frequency range applies.

 These guidelines may not apply in all situations. 

Electromagnetic propagation is affected by absorption and reflection 
from structures, objects, and people.
