Note 1: 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.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) and land mobile
radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To access 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 (equipment or system) is used exceeds the applicable RF compliance level above, the (equipment or
system) should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the Pulsar MS unit.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF
COMMUNICATION EQUIPMENT AND PULSAR MS
Pulsar MS is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of Pulsar MS can help preventing
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and Pulsar MS as recommended below,
according to the maximum output power of the communications equipment.

For transmitters rates at maximum output power not listed above, the recommended
separation distance 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:
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.
