Field strengths from fixed transmitters, such as base stations for radio (cellular/
cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To
assess the electromagnetic environment due to fixed RF transmitters, an electro-
magnetic site survey should be considered. If the measured field strength in the
location in which the model CanalPro X-Move is used exceeds the applicable RF
compliance level above, the model CanalPro X-Move should be observed to verify
normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the model CanalPro X-Move.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
3V/m.
Table 4: Recommended separation distances between portable and
mobile RF communications equipment and the model CanalPro X-Move
The model CanalPro X-Move is intended for use in electromagnetic environment
in which radiated RF disturbances is controlled. The customer or the user of
the model CanalPro X-Move can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the model CanalPro X-Move
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) accordable 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.
