Guidance and manufacturer statement - Electromagnetic Immunity
The ApexPilot is intended for use in the electromagnetic environment specified below. The
customer or the user of the ApexPilot shouId assure that is used in such an environment.

Field strengths from fixed RF

NOTE
: UT is the ac. mains voltage prior to application of the test level.
NOTE 1
: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2
:These guidelines may not apply in at I 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 (celIular/ cord less)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast can not 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 ApexPilot is used exceeds the
applicable RF compliance level above, the ApexPilot should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the ApexPilot.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
