The ClearChart 4P is intended for use in the electromagnetic environment in which radiated
RF disturbances are controlled. The customer or user of the ClearChart 4P can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF Communications Equipment and the ClearChart 4P 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 absorp-
tion and reflection from structures, objects, and people.
