GUIDANCE AND MANUFACTURER’S DECLARATION - ELECTROMAGNETIC IMMUNITY
The MTI Stretcher Bed is intended for use in the electromagnetic environment specified below. The customer or the user of the
MTI Stretcher Bed 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 MTI Stretcher Bed, including cables, than
the recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance:
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) according to the transmitter manufacturer and d is the
recommended separation in meters (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:
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.
NOTICE/AVIS
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 MTI Stretcher Bed is used exceeds the applicable RF compliance level above, the MTI
Stretcher Bed should be observed to verify normal operation.
a
Les forces de champ des émetteurs fixes, telles que les stations de base pour les téléphones radio (cellulaires / sans fil) et
les radios mobiles terrestres, la radio amateur, les émissions de radio AM et FM et les émissions de télévision ne peuvent pas
être prédites avec précision. Pour évaluer le environnement électromagnétique dû aux émetteurs RF fixes, une étude de site
électromagnétique doit être envisagée. Si le mesuré la résistance au champ dans le lieu où le fauteuil de procédure MTI est utilisé
dépasse le niveau de conformité RF applicable indiqué ci-dessus, le MTI Le président de procédure doit être observé pour vérifier
le bon fonctionnement.
If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the MTI Stretcher
Bed.
b
Over the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m.
