3: Operating the Device
Turning the Efficia DFM100 On
To turn the Efficia DFM100 on, turn the Therapy knob to the desired mode of operation.
Turning the Efficia DFM100 Off
To turn the Efficia DFM100 off, turn the Therapy knob to the OFF position. If you turn the device
off while in a clinical mode, the Efficia DFM100 enters the Continued Use Period (see
on page 42). The screen displays a 10-second countdown before turning off.
NOTE: You should leave the device plugged in to keep the battery charged and allow automated diagnostic
tests to run periodically.
When no AC power is connected and the battery charge level drops to a critically low level, the
Efficia DFM100 can no longer guarantee correct operation. The defibrillator generates an Imminent
Shutdown alarm. You have approximately one minute to connect the device to AC power before it
If power is returned within 30 seconds after a complete loss of power and the Therapy knob is not in
the OFF position, the Efficia DFM100 automatically turns back on, user settings are restored to
their values prior to the shutdown, the Efficia DFM100 continues to use the current Event
Summary and the duration of the shutdown is recorded in the Event Summary.
WARNING: Pacing is not automatically restarted after the Efficia DFM100 recovers from a power loss. You must
restart pacing manually.
If the Efficia DFM100 restarts after 30 seconds and the Therapy knob is not in the OFF position, all
settings are returned to their configured values, a new Event Summary starts and you are notified
that the previous Event Summary was closed.
NOTE: Based on the software's status when power was lost, alarm settings in effect at the time of power loss
may be restored in situations where power is returned up to 45 seconds after a power loss.
