Guidance and manufacturer’s declaration – electromagnetic immunity
The CO
2
EFFICIENT ENDOSCOPIC INSUFFLATOR is intended for use in the electromagnetic environment specified
below. The customer or the user of the CO
2
EFFICIENT ENDOSCOPIC INSUFFLATOR should assure that it is used
in such an environment.

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 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 CO
2
EFFICIENT ENDOSCOPIC
INSUFFLATOR is used exceeds the applicable RF compliance level above, the CO
2
EFFICIENT ENDOSCOPIC
INSUFFLATOR should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the CO
2
EFFICIENT ENDOSCOPIC
INSUFFLATOR.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m
