considered. If the measured field strength in the location in which the
device is used exceeds the applicable RF compliance level above, the
device should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
re-orienting or relocating the device.
b.
Over the frequency range 150 kHz to 80 MHz, the field strengths should
be less than 3 V/m.
Recommended separation distances between portable and mobile
RF communications equipment and the device:
The device is intended for
use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or 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 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 power rating of the transmitter in watts(W) according to the transmitter
manufacturer.
Note 1: At 80 MHz and 800 MHz, the higher frequency range applied.
Note 2: These guidelines may not apply in all situations. Electromagnetic
propagat
ion is affected by absorption and reflection of the structures, objects and
people.
