Recommended separation distances between portable and mobile RF communications
equipment and the VPAP Malibu
The VPAP Malibu is intended for use in an environment in which radiated RF disturbances are controlled.
The customer or the user of the VPAP Malibu can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters) and the
VPAP Malibu as recommended below, according to the maximum output power of the communications
equipment.

100 11.70 3.50 7.00
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: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
