8. Important information
At 80 MHz and 800 MHz, t he 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 Coronis 3MP LED Display is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer of the user of the Coronis 3MP LED Display can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the Coronis 3MP LED Display as recommended below,
according to the maximum output power of the communications equipment.

On the device or power supply, you may find the following symbols (nonrestrictive list):
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.
