TM
WL-090
The WL-090 is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the WL-090 can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the WL-
090 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 metres (m) can be determined 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.
Note1: At 80 MHz and 800 MHz, the separation distance for the higher frequency
range applies.
Note2: These guidelines may not apply in all situations. Electromagnetic propagation
