Field strengths from fixed transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance levels (V1

Interference may occur in the vicinity of
equipment marked with the following symbol:
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.
Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and this device. This device and system are NOT
Life-Supporting
This device is intended for use in the electromagnetic environment in which radiated disturbances are controlled. The
customer or user of this device can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF Communications Equipment and the device as recommended below, according to the
maximum output power of the communications equipment.
