Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and this device. This device and system are NOT
Life-Supporting
This device is intended for use in the electromagnetic environment in which radiated
disturbances are controlled. The customer or user of this device can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF Communications Equipment and the device 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.
