2 - FIO2 ALARM LIMITS

• The LifeWindow™ Lite LW8 FIO2 alarm limits default and range is:

FIO2 Upper Limit: OFF Range: 5 to 100%
  FIO2 Lower Limit:       20% Range: 0 to 95%

• In the FIO2 menu, select the Upper and Lower alarm limits. To return to the factory DEFAULT
  alarm limits, go to the SYSTEM menu and press the Load Factory Default Settings.

3 - FIO2 ALARM MESSAGES

FIO2 HIGH – Indicates the FIO2 reading is higher than the Upper Limit set.

FIO2 LOW – Indicates the FIO2 reading is lower than the Lower Limit set.
