WD 300
The KARL STORZ AIDA
® WD
300 are intended for use in an electromagnetic environment in which the
RF disturbances are controlled. The user of the device can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the device – as a function of the output power of the communication device, as shown
below.

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: These guidelines may not apply in all situations. The propagation of electromagnetic quantities is
affected by absorptions and reflections of buildings, objects and persons.
