Electromagnetic Environment - Guidance
• Maintain humidity in the use environment to at
least 50% relative humidity.
• Floors should be wood, concrete, or ceramic tile.
If floors are covered with synthetic material, DJO
recommends implementing additional controls to
maintain relative humidity to at least 50%.
• Communicate these ESD-precautionary
procedures to healthcare staff, contractors,
visitors and patients.
Mains power quality should be that of a typical
commercial or hospital environment.
Mains power quality should be that of a typical
commercial or hospital environment.
Mains power quality should be that of a typical
commercial or hospital environment. If the user
of the Intelect® Legend 2 requires continued
operation during power mains interruptions, it
is recommended that the Intelect® Legend 2 be
powered from an uninterruptible power supply or
a battery.
Power frequency magnetic fields should be at
levels characteristic of a typical location in a typical
commercial or hospital environment.
