The Defibtech Lifeline verbally tells you what is wrong with the unit if it encounters a problem following a self-test. Both electrode pads and the battery have the expiry date printed.

Common Error Causes

A common error is the electrode pads being unnecessarily unplugged from the unit. When these are plugged back in, the battery does not recognise that they are present and thus causes the device to beep. A battery low in power will also cause the device to bleep.

Please see below a quick guide to checking the defibrillator:

  • Remove the electrode pads and battery
  • Check all items are valid and still in date
  • Check the large battery has a 9V battery included
  • Plug the electrode pads back in
  • Reinsert the battery
  • The defibrillator, at this point, should do a battery test, and say “battery OK” when completed
  • Then owners need to perform a self-test on the unit. To do this hold down the power button until the unit says “Performing unit self-test” and then will ask for the user to press the shock button (the unit will not ask the user to press the shock button if it is an AUTO unit, with no shock button).The unit will then run through a few internal tests for 10-15 seconds
  • Once completed, in 99% of cases, the unit will say “Unit OK” and all visual audible warnings will stop. If it doesn’t, the unit will either advise how to fix the error, IE “Replace 9V Battery”, or will give a service code, which indicates a software / firmware issue. 

250 - No - Means battery was inserted prior to the pads - you should take them both out and insert the pads first.

Please ensure that you do the manual self-test. Martek require hearing the customer do this test to ensure they can claim on the defibrillator's limited warranty. Before Martek would collect the unit, they will have the customer perform the self-test. The customer is required to cooperate and perform this as they may incur a cost of around £150.
