RECOMMENDED SEPARATION DISTANCES BETWEEN
PORTABLE AND MOBILE RF COMMUNICATIONS EQUIPMENT
AND POWERDOT PD-01 DEVICE
The PowerDot PD-01 device is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer
or the user of the PowerDot PD-01 device can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the PowerDot PD-01 device
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 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.
