Interference may occur in
the vicinity of equipment
marked with symbol:
At 80 MHz and 800 MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is af-
fected by absorption and reflection from structures, objects and people.
Recommended separation distance
The Eonis display is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer of the user of the Eonis display can help prevent electromagnetic interfer-
ence by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Eonis display as recommended below, according to the maximum output power of
the communications equipment.

At 80 MHz and 800 MHz, the separation distance f or the higher frequency range applies.
3. 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 Eonis display is used exceeds the applicable RF compliance level above, the Eonis display should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the Eonis display.
4. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than3V/m.
5. 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.
