Recommended separation distance between portable and mobile RF communications equipment and the
CG155f
The CG155f is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the CG155f can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the CG155f as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d in meters (m) can be estimated using the equation applicable to the frequency of the transmitter,
where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is aected by
absorption and reflection from structures, objects and people.
WARNING: The symbol on this product means that it’s an electronic product and following the
European directive 2012/19/EU the electronic products have to be dispose on your local recycling
centre for safe treatment.
This instrument is covered by a 2 year guarantee from the date of purchase. Batteries, cu and

Portable and mobile RF communications
equipment should be used no closer to
any part of the CG155f, 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 800
MHz, d = 2,3 √P 800MHz 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 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 Interference
may occur in the vicinity of equipment
marked with the following symbol:
NOTE1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2: These guidelines may not apply in all situations. Electromagnetic propagation is aected 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 CG155f is used exceeds the applicable RF compliance level above, the CG155f should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the CG155f.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
