For transmitters rated at a maximum output power not listed above, the recommended separation
distanced 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.
Recommended separation distances between portable and mobile
RF communications equipment and the Welch Allyn KleenSpec®
Corded Illumination System
The Welch Allyn KleenSpec® Corded Illumination System is intended for use in
an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or user of the Welch Allyn KleenSpec® Corded
Illumination System can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Welch Allyn KleenSpec®
Corded Illumination System as recommended below, according to the
maximum output power of the communications equipment.
