Note: Once the monitor is silenced, the N-600x sounds a piezo tone every three
minutes as a reminder of the primary speaker failure condition. The
N-600x also sounds the piezo tone to annunciate low, medium and high
priority alarms during this time. If an N-600x monitor is reporting a primary
speaker failure is powered off, it cannot be powered on again.
WARNING: If an N-600x reports a primary speaker failure, do not use the
monitor longer than necessary to ensure patient safety. Contact a qualified
service personnel, your local Nellcor representative, or Nellcor's Technical
Services Department for assistance.
