TotalAlert Infinity™ HTM Medical Gas Notification System
Recommended separation distances between
portable and mobile RF communications equipment and the TotalAlert Infinity
The TotalAlert Infinity is intended for use in the electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the TotalAlert Infinity can help
prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the TotalAlert Infinity as recom-
mended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended sepa-
ration distance d in metres (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 affected
by absorption and reflection from structures, objects and people.
