Ampere™ Generator Instructions for Use
International Edition Rev. A 100081509-en
Electromagnetic Immunity Declaration II
The EnSite ™ Velocity ™ Cardiac Mapping System Amplifier and Workstation are intended for use in the electromagnetic environment
specified below. The customer or the user of the EnSite™ Velocity™ Cardiac Mapping System Amplifier / Workstation 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 Ampere ™ Generator,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
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
distance 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.
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
Cool Point ™ Irrigation Pump is used exceeds the applicable RF compliance level above, the Cool Point ™ Irrigation Pump should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the Cool Point ™ Irrigation Pump.
