are

intended

for

use

in

electromagnetic

environments

where

RF

are

controlled

.

Depending

on

the

maximum

rated

power

of

the

communication

device

,

the

purchaser

or

user

can

prevent

electromagnetic

interference

by

maintaining

the

minimum

devices

(

not

listed

in

the

table

above

,

the

recommended

isolation

distance

d

is

in

meters

(

)

,

which

can

be

determined

by

the

formula

in

the

:

At

:

These

guidelines

may

not

be

suitable

for

all

situations

.

Electromagnetic
