8 Press the [Start] soft key to begin calibrating.
The calibration procedure charges the battery to full capacity, drains the battery in preparation for
calibration, calibrates the battery, and then charges it again following calibration. Once you see the
message, Calibration Complete. The battery charges faster when the device is turned off, you may
turn the Therapy Knob to Off to allow the battery to charge more quickly.
Calibration takes approximately 11 hours to complete in the HeartStart MRx. Progress is shown on the
display. It takes significantly less time to calibrate in a Philips-approved battery support system.
Monitoring/therapy functions are not available during battery calibration in the MRx. If it is necessary
to terminate calibration to resume clinical use, press the [Cancel] soft key.
WARNING Battery calibration is terminated if external power or the battery being calibrated is removed before the
calibration process is completed. If calibration is terminated, the battery will not be calibrated and its
capacity may be very low.
Calibration Results
At the completion of battery calibration, a Pass or Fail is reported to indicate whether calibration
completed successfully. In addition, an estimate of battery capacity is provided so that you can
determine if the battery is fit for use. If the capacity is:
•>
80% continue to use the battery
• < 80% discard the battery
NOTE After successfully calibrating your batteries, perform an Operational Check. You may be prompted to
recalibrate depending upon the condition of your battery.
Storing Batteries
Batteries should be rotated regularly to ensure even usage. When storing batteries, make sure that the
battery terminals do not come in contact with metallic objects.
If batteries are stored for an extended period of time, they should be stored in a cool place, with a
partial charge of 20% (1 LED illuminated) to 40% (2 LED’s illuminated) capacity. Storing batteries in
a cool place slows the aging process. The ideal storage temperature is 15
o
C (60
o
F). Batteries should not
be stored at temperatures outside the range of -20
o
C (-4
o
F) to 60
o
C (140
o
F).
CAUTION • Do not store batteries in the HeartStart MRx if it is out of service for an extended period of time.
• Storing batteries at temperatures above 38
o
C (100
o
F) for extended periods of time significantly
reduces a battery’s life expectancy.
Stored batteries should be charged every 2 months to 20% - 40% of their full capacity. They should be
charged to full capacity prior to use.
