recommended that Cala
Trio be powered from an
uninterruptible power supply
or a battery.

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

d = 2.3√P 800 MHz to 2.7 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 metres
(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
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 location in which Cala Trio
is used exceeds the applicable RF compliance level above, Cala Trio should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating Cala Trio.
b
Over the frequency range 150 kHz to 80 MHz,
field strengths should be less than 3 V/m.

a) For some services, only the uplink frequencies are included.
b) The carrier shall be modulated using a 50 % duty cycle square wave signal.
c) As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because while it does not represent actual modulation, it
would be worst case.
