Operation
CAUTION: To prevent the premature depletion and reduced life
expectancy of the battery, store the ventilator with AC power
connected and the ON/OFF switch in the ON (I) position. When the
ventilator is stored disconnected from AC power with the power
ON/OFF switch ON (I) and in standby, the battery may become
depleted within two weeks. When the ventilator is stored with the
ON/OFF switch in the OFF (O) position, the battery typically
becomes depleted in three months. For maximum battery
performance, a new battery or a battery that has been in storage
should be fully charged and discharged two to three times.
If a 343 error code is displayed, contact Service. The battery needs
replacement.
4. Once the system begins normal operation, disconnect the power
cord from wall power. Verify the following indicators are
functioning:
• Yellow ON BATTERY indicator turns on.
• ON AC POWER and green BATTERY CHARGING indicators
turn off.
• Red ALARM indicator flashes, audible alarm sounds.
5. Press ALARM RESET. Verify that the ALARM LED and audible
alarm turn off.
The audible alarm sounds (beeps) once a minute, alerting the
user that unit is running on the internal battery.
6. Reconnect AC power. Verify that the ON AC POWER LED is on
and the ON BATTERY LED is off. Press ALARM SILENCE and
verify that the yellow ALARM SILENCE indicator turns on. Press
ALARM RESET to cancel the silence and verify that ALARM
SILENCE indicator turns off.
7. Use the CHANGE SCREEN, UP/DOWN arrow, ENTER, and
CANCEL keys to step through screens and verify the operation
of each key.
8. Enter CPAP mode with a patient circuit attached and allow the
ventilator to deliver gas for more than 15 seconds. Verify that a
Disconnect (i.e., patient disconnect) alarm occurs.
