Electromagnetic Compatibility
Guidance and manufacturer’s declaration – electromagnetic immunity
The DoloBravo unit is intended for use in the electromagnetic environment specied below.
The customer or the user of the DoloBravo should ensure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to
any part of the DoloBravo unit, including
cables, than the recommended separation
distance calculated from the equation appli-
cable 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 xed RF
transmitters, as determined by an electro-
magnetic 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 affec-
ted by absorption and reection from structures, objects and people.
A) Field strengths from xed transmitters, such as base stations for radio (cellular/cordless) tele-
phones 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 xed RF transmitters, an electromagnetic site survey should be considered. If the measured
eld strength in the location in which the DoloBravo unit is used exceeds the applicable RF
compliance level above, the DoloBravo unit should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting
or relocating the DoloBravo unit.
B) Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3V/m.
