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
TRV is used exceeds the applicable RF compliance level above, the TRV
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the
TRV.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
To ensure compliance with the EMC requirements as specified in IEC 60601-1-2, it is essential to use
only the following accessories:
• Foot switch
• Charging battery
Conformance to the EMC requirements as specified in IEC 60601-1-2 is ensured if the cable types and
cable lengths are as specified below:
• No specific cables used
