Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The transmitter is intended for use in the electromagnetic environment specified be-
low. The customer or user of the transmitter should assure that it is used in such an
electromagnetic environment.
Immunity Test
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 broadcasts and TV broadcast cannot be pre-
dicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF trans-
mitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the transmitter is used exceeds the applicable RF compliance level above, the trans-
mitter should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the transmitter.
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
communications equipment and the transmitter
The transmitter is intended for use in an electromagnetic environment in which radi-
ated RF disturbances are controlled. The customer or the transmitter users can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment and the transmitter as recommen-
ded below, according to the maximum output power of the communications equip-
ment.

For transmitters rated at a maximum output power not listed above, the recommended separation dis-
tance d in meters (m) can be estimated using the equation applicable to the frequency of the transmit-
ter, where p is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
Note:
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects, and people.
