Note1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note2: These guidelines may not apply in all situations.
Electromagnetic propagation is affected by absorption and reflection from structures,
objects, and people.
Field strengths from fixed RF transmitters, such as base stations for radio (cellular/
a
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 electromagnetic site survey
should be considered. If the measured field strength in the location in which device is
used exceeds the applicable RF compliance level above, device should be observed to
verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating device.
Over the frequency range 0.15 MHz to 80 MHz, field strengths should be less than 3 V/m.

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