Recommended Separation Distances

Refer to the following table for recommended separation distances
between the ER920W and portable and mobile RF commu nications
equipment.

The ER920W is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The user of the ER9xx
can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment
(transmitters) and the ER9xx as recommended below, according to the
maximum output power of the communications equipment.

10 3,8 3,8 7,3

100 12 12 23

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.

NOTE1: 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.
