Note 1 : At 80 MHz and 800 MHz, 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.
a
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 TB 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 the CS 2400P model device is used exceeds the applicable
RF compliance level above, the CS 2400P model device should be observed to verify normal
operating. If abnormal performance is observed, additional measures may be necessary such as
reorienting or relocating the CS 2400P model device.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less that 10 V/m.
Recommended separation distances between portable and mobile RF
communications equipment and the CS 2400P
Recommended separation distances between portable and mobile RF communications equipment
and the CS 2400P model device
The CS 2400P model device is intended f
o
r use in an electromagnetic environment in which radiated
RF disturbance are controlled. The customer or the CS 2400P model device can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the CS 2400P model 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 separation distance for the higher frequency range applies.
