If the ventilator is running , the internal battery reserve is momentarily displayed as a percentage. Then, after
the ventilator calculates the battery time remaining (which takes about two minutes, depending on the power
consumption of the ventilator), the internal battery reserve is then displayed in hours and minutes (rounded to
the nearest fifteen minutes). Refer to
Figure 6-3 .
Figure 6-3. Battery Reserve Capacity in Hours and Minutes
The “LOW BATTERY“ and “EMPTY BATTERY“ alarms (refer to chapter 3, “Alarms and Troubleshooting” ) are
triggered when the internal battery reserve is reduced.
