If stored for extended periods with batteries installed, inspect both batteries prior to use to
ensure they have not corroded.
•
Dispose of used batteries properly.
2.4 Important Safety Features
Changing a battery during operation -- Should a low battery level occur during resuscitation
efforts, either battery may be removed and replaced, (one at a time), from its compartment and a fresh
battery can be “hot swapped’ providing uninterrupted CPR.
WARNING: The “Hot Swap” should ONLY be performed when it is KNOWN
that both batteries are installed and have equal energy. If no battery power is
available, the device will stop without resetting. This could result in a “piston
down” position requiring removal of the O2 Supply Hose from the base of the
device to release the piston.
To “Hot Swap” the battery
1. Remove only one battery tray from either side of the Life-Stat
®
allowing the battery installed
on the opposing side to continue to power the device.
2. Remove the used battery by pushing it back against the retaining spring and lifting up.
3. Insert a fresh battery in its place ensuring it is oriented properly (+ on left, - on right) per the
diagram embossed on the bottom of the tray.
4. Re-insert the tray until a click is heard to ensure it is seated properly.
5. Discard the used battery appropriately when convenient.
The opposing battery may be ‘hot-swapped’ also following the above steps at this time. If it is not
replaced immediately, install a fresh battery as soon as possible to ensure both batteries are fresh.
After replacement of either or both batteries, the LOW BATT LED will remain illuminated for
approximately 2 - 5 minutes.
Auto Shutdown feature -- When the batteries reach a critical low level condition, the Life-Stat
®
will
initiate an auto shutdown procedure. If the Life-Stat
®
is not physically turned off via the STOP/OFF
button on the System Control (#1) keypad –or- the batteries are not ‘hot-swapped’ out as explained
above, the compressor piston will return to the ‘up’ position, the ventilator will turn off, and the
electronic control module will automatically shut down.
Also, if the unit is turned on (the START/ON button is pressed) but no CPR mode (30;2 or CCV) is
selected within 16 minutes, the device will shut down to conserve the batteries.
Service Interval Indicator
— After the Life-Stat
®
has delivered over 1,000,000 (1 million) cycles, the
START/ON LED indicator will flash. It is recommended to return the device to the factory for service
after this occurs. The Life-Stat
®
will continue to function, however diminished performance may
result if the recommended service is not performed to replace potentially worn components.
