should be used no closer to
any part of the Model 240
Audiometer, including cables,
than the recommended
separation distance
calculated from the equation
applicable to the frequency of
the transmitter.
Recommended separation
distance
d = 1.2√P
d = 1.2√P 80MHz to 800MHz
d = 2.3√P 800MHz to 2.5GHz
where P is the maximum
output power rating of the
transmitter in Watts (W)
according to the transmitter
manufacturer and d is the
recommended separation
distance in metres (m).
