N/A The main power quality should be similar to that of a typical
commercial or hospital environment. If the user of the
equipment or system requires continued operation during
power main interruptions, it is recommended that the
equipment or system be powered from an uninterruptible
power supply or a battery.
30 A/m Power frequency magnetic fields should be at levels
50 Hz or 60 Hz characteristic of a typical location in a typical commercial or
hospital environment.
