Recommended isolation distance between portable and mobile radio frequency
communication equipment and this product
This product is expected to be used in a controlled electromagnetic environment
with RF radiation disturbance. According to the maximum output power of the
communication equipment, the purchaser or user of this product can prevent
electromagnetic interference by maintaining the minimum distance between the
portable and mobile radio frequency communication equipment (transmitter)
and the product

The maximum rated power of the transmitter not listed in the table above is
recommended for isolation distance d, in meters (m), which can be determined
by the formula in the corresponding transmitter frequency bar. here p is the
maximum rated output power of the transmitter provided by the transmitter
manufacturer in watts (W) units.
Remark 1 ： The formula of higher frequency band should be used at 80 MHz
and 800 MHz frequency.
Remark 2 ： These guidelines may not be suitable for all situations.
Electromagnetic propagation is affected by the absorption and reflection of
buildings, objects and human bodies.
