NOTE:
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE:
These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) tele-
phones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast can-
not 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 MR2416 is used exceeds the applicable RF compliance level
above, the MR2416 should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the MR2416.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distance
The MR2416 display is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer of the user or the MR2416 display
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
MR2416 display 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:
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE:
These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
