Observe the battery charge level before the ventilator is used
on a patient, and before unplugging the ventilator for trans-
port or other purposes.
• A green symbol indicates a fully charged battery.
• A red and green symbol indicates a partially charged bat-
tery.
• If a battery symbol is crossed out with a red X, the battery
is discharged or defective.
If the batteries are not fully charged, recharge them by plug-
ging in the ventilator for a minimum of 15 hours (for the inter-
nal battery) or 7 hours (for an extended battery pack), or until
the battery charge level is 80 to 100%. If the internal battery is
not fully charged at this time, have the ventilator serviced by
authorized service personnel.
The extended battery pack requires a periodic recalibration.
Use the designated battery calibrator for the extended battery.
