Guidance and manufacture's declaration – electromagnetic immunity
The SE-601 Electrocardiograph is intended for use in the electromagnetic environment
specified below. The customer or the user of SE-601 Electrocardiograph should assure that it is
used in such an environment.

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 SE-601
Electrocardiograph is used exceeds the applicable RF compliance level above, the
SE-601 Electrocardiograph should be observed to verify normal operation. If abnormal
