Electromagnetic propagation isaffected by the reflection from structures, objects, and people.• aField strengths from fixed transmitters, such as base stations for radio(cellular/cordless) telephones and land mobile radio, AM and FM radio broadcast,and TV broadcast cannot be predicted theoretically with accuracy. To assess theelectromagnetic environment due to fixed RF transmitters, consider conducting anelectromagnetic site survey. If the measured field strength in the location in whichthe system is used exceeds the applicable RF compliance level listed in this table,observe the system to verify normal operation. If abnormal performance is observed,additional measures may be necessary, such as re-orienting or relocating the system.• Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3V/m for Multilink and Value Lead Sets, and less than 1 V/m for the KISS Lead Sets.2053535-003C MAC™ 2000 ECG Analysis System 169
