CS624 Qseal-extra Operator´s manual
Guidance and Manufacturer’s Declaration – Electromagnetic Immunity
The CS624 Qseal-extra is intended for use in the electromagnetic environment specied below.
The customer or the user of the Qseal-extra should assure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to
any part of the CS624 Qseal-extra includ-
ing cables than the recommended separa-
tion distance calculated from the equation
applicable to the frequency of the trans-
mitter.

d = 1.17 √P
d = 1.17 √P 80 MHz to 800 MHz
d = 2.33 √P 800 MHz to 2.5 GHz
Where P is the maximum output power
rating of the transmitter in watts (W) ac-
cording to the transmitter manufacturer
and d is the recommended separation
distance in meters (m).
Field strengths from xed RF transmitters,
as determined by an electromagnetic site
survey,
a
should be less than the compli-
ance level in each frequency range.
b
Interference may occur in the vicinity of
equipment marked
with the following
symbol:
NOTE 1 At 80MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is af-
fected by absorption and reection 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 meas-
ured eld strength in the location in which the CS624 Qseal-extra is used exceeds the applicable
RF compliance level above, it should be observed to verify normal operation. If abnormal per-
formance is observed, additional measures may be necessary, such as reorienting or relocating
the CS624 Qseal-extra.
b
Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
