Guidance and manufacturer's declaration – electromagnetic immunity
The Rehalito unit is intended for use in the electromagnetic environment specified below. The
customer or the user of the Rehalito should ensure that it is used in such an environment.

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 the Rehalito unit is used
exceeds the applicable RF compliance level above, the Rehalito unit should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Rehalito unit.
B) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1]
V/m.

Electromagnetic environment – guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the Rehalito unit, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d=1.2√P
d=1.2√P 80MHz to 800MHz
d=2.3 √P 800MHz to 2.5 GHz
where P is the maximum output power
rating of the transmitter in watts (W) accor-
ding to the transmitter manufacturer and d
is the recommended separation distance in
metres (m). Field strengths from fixed RF
transmitters, as determined by an electro-
magnetic site survey,
less than the compliance level in each
frequency range.
