Recommended separation distances between portable and mobile RF communications
equipment and the CGM MB-1901.
The CGM MB-1901 is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The user of the CGM MB-1901 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment(transmitters) and the CGM MB-1901 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.
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.

Note 1) These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
Note 2) It is essential that the actual shielding effectiveness and filter attenuation of the shielded location be
verified to assure that they meet the minimum specification.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy.
To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should
be considered. If the measured field strength in the location in which the EUT is used exceeds the applicable
RF compliance level above, the EUT should be observed to verifynormal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the EUT.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V 1] V/m.
Electromagnetic
environment - guidance
CGM MB-1901 must be used only in a
shielded location with a minimum
RF shielding effectiveness and, for each
cable that enters the shielded location
with a minimum RF shielding
effectiveness and, for each cable that
enters the shielded location.
Field strengths outside the shielded
location from fixed RF transmitters, as
determined by an electromagnetic
site survey, should be less than 10V/m.a
