controlled. The customer or the user of the WarmAir

, Model 135 can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters) and the WarmAir

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.
Supplemental certification or EMC information available on request.
