the Fimet F1 requires continued operation during
power mains interruptions, it is recommended to
power the Fimet F1 from an uninterruptible power
supply or a battery.

Portable and mobile RF communications equipment
should be used no closer to any part of the F1
product, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance

80 MHz to 800 MHz
Pd *33.2=
800 MHz to 2,5 GHz
where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey (a),
should be less than the compliance level in each
frequency range (b).
Interference may occur in the vicinity of equipment
marked with the following symbol:
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 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 use
location of the Fimet F1 exceeds the applicable RF compliance level above, the Fimet F1 should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Fimet F1.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
