SECTION 1—SAFETY

Radio Frequency Interference
WARNING
Risk of Injury or Damage
To reduce the risk of injury or product damage from interference with wireless
equipment:
Keep concentrator at least 9.8 ft (3.0 m) away from wireless communication equip-
ment such as wireless home network devices, mobile phones, cordless phones and
base stations, walkie-talkies, etc.
This equipment has been tested and found to comply with EMC limits specified by IEC/
EN 60601-1-2. These limits are designed to provide a reasonable protection against
electromagnetic interference in a typical medical installation.
Other devices may experience interference from even the low levels of electromagnetic
emissions permitted by the above standards. To determine if the emissions from the
concentrator are causing the interference, turn the concentrator Off. If the interference
with the other device(s) stops, then the concentrator is causing the interference. In such
rare cases, interference may be reduced or corrected by one of the following measures:
• Reposition, relocate, or increase the separation between the equipment.
• Connect the equipment into an outlet on a circuit different from that to which the
other device(s) is connected.
