Maintaining your Philips OnSite AED

Instructions for Replacing Electrodes in the Philips OnSite AED

  • Locate the latch at the top edge of the OnSite and slide it to the side (if you’re looking at the front of the AED, the latch moves from Left to Right).
  • This should release the old electrodes cartridge. Use your finger to pull on the yellow plastic shell to remove the electrodes. If you have difficulty, turn the AED upside down while pulling the latch and the old electrodes should fall out.
  • Follow instructions on white/red foil of new electrodes for instruction:
    • Tear open foil along dotted line.
    • Insert cartridge into OnSite by seating the base of the electrodes and then pushing the top of the cartridge (clear plastic) down until the cartridge “clicks” in.
    • The device should audibly recognize that adult electrodes were inserted.

Once you have changed the pads in your AED, please update these expiration dates in the SMART Track system.

Replacing the Battery in the Philips OnSite AED

  • Unzip red case, open it, and remove the entire AED from the case
  • Lay the AED face down (the clear plastic side should be against the ground).
  • Remove the old battery. The battery is on the left side of the AED (when looking at it face down) and can be removed by pulling the top tab and pulling the battery out.
  • Insert the new battery into the battery compartment
  • Once inserted, the OnSite will automatically run a self-test
    • Press the Shock button when instructed to do so
    • When the self-test is over, the OnSite will report the result and tell you to push the green On/Off button in case of an emergency (Do NOT push the green button unless this is an actual emergency)
    • The OnSite will then go into standby mode
    • The green Ready light will be blinking (about once every 3 seconds) to show the OnSite is ready for use
  • Return the AED to the red case

Once you have changed the battery in your AED, please update the expiration date in the SMART Track system.
