7.4 Battery Test
WARNING:
NOTE:
A
Low Battery
or
Battery Depleted
alarm during the pre-operational check
indicates that the battery must be charged. A
Batt. Charge Failure
alarm
indicates that the battery may be fully depleted. Recharge the battery
before proceeding. If the battery does not begin to charge after one hour
and the
Batt. Charge Failure
persists, replace the battery.
NOTE:
Battery alarms sound near the end of the battery test. Gas delivery
continues until the battery is depleted.
Test the battery once a month. A fully charged battery is designed to support
ventilator operation for 45 minutes at default settings:
Replace the battery if it cannot do so.
The 3.7 amp-hour (Ah) nickel metal hydride (NiMH) battery provides 45
minutes of operation at default settings. System automatically activates the
battery charge cycle when connected to AC power and the ON/OFF switch is
ON ( | ) during normal operation or Standby mode.
Recharge time is typically under 5 hours, but may extend further depending on
machine settings if operating on battery prior to recharge, or if operating in
elevated ambient temperature (above 28 °C). The green CHARGING LED turns
off when battery recharge is complete.
