is intended for use in the electromagnetic environment specified below. The customer or the user of
the
ECG Check
should assure that it is used in such an environment.

3 V RMS outside the
ISM band, 6 V RMS in

radio bands
150 kHz to 80 MHz
Not applicable
Portable and mobile RF communications equipment should be
used no closer to any part of the ECG Check, 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
metres (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
