The SL 20i is intended for use in the electromagnetic environment in which radiated RF
disturbance are controlled. The customer or user of the SL 20i can help prevent Electromagnetic
interference by maintaining a minimum distance between portable and mobile RF Communications
Equipment (transmitters) and the SL 20i 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 80MHz 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.
