TotalAlert Infinity™ HTM Medical Gas Notification System
Guidance and manufacturer's declaration - electromagnetic immunity
The TotalAlert Infinity is intended for use in the electromagnetic environment specified below.
The customer or the user of the TotalAlert Infinity should assure that it is used in such an environment.

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, and electromagnetic site survey should be considered. If the
measured field strength in the location in which the TotalAlert Infinity is used exceeds the applicable RF compliance level above, the
TotalAlert Infinity should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the TotalAlert Infinity.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Power frequency magnetic fields should be at
levels characteristic of a typical location in a typi-
cal commercial or hospital environment.
Portable and mobile RF communications equip-
ment should be used no closer to any part of
the TotalAlert Infinity, 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 80 MHz to 800 MHz
d = 2,3√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 recom-
mended separation distance in metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance
a
level in each frequency range.
Interference may occur in the vicinity of equip-
b
ment marked with the following symbol:
