Recommended Separation Distances
Recommended separation distances between portable and mobile RF communications equipment and the
Pulmonex. Table 6
The Pulmonex is intended for use in the electromagnetic environment in which radiated RF disturbance are
controlled. The customer or the user of the Pulmonex can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communication equipment (transmitters) and
the Pulmonex as recommended below, according to the maximum output power of the communication 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 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.
Operating Temperature
Do not expose the equipment to a temperature change of more than 5° F (3° C) per hour.
limits of low and high operating temperature ranges are 59° to 86° F (15° C to 30° C).
