NOTE 1: At 80 MHz and 800 MHz, 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.
a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the DeVilbiss DV6WM
Wireless Modem is used exceeds the applicable RF compliance level above, the DeVilbiss
DV6WM Wireless Modem should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or
relocating the DeVilbiss DV6WM Wireless Modem.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.

Recommended Separation Distances Between Portable and
Mobile RF Communications Equipment and this device. This
device and system are NOT Life-Supporting
The DeVilbiss DV6WM Wireless Modem is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the user of
the DeVilbiss DV6WM Wireless Modem can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the DeVilbiss DV6WM Wireless Modem 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 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.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range
applies.
NOTE 2: The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz
are 6.765 MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and
40.66 MHz to 40.70 MHz.
NOTE 3: An additional factor of 10/3 has been incorporated into the formulae used in
calculating the recommended separation distance for transmitters in the ISM frequency
bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz to
decrease the likelihood that mobile/portable communications equipment could cause
interference if it is inadvertently brought into patient areas.
NOTE 4: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
