Recommended separation distance between portable and mobile
The R26M/R36M middle ear analyzer is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the R26M/R36M can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the R26M/R36M 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 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.
