I need to know the RESET procedure to get rid of the "service wrench" indicator on the units.After testing with Defib analyzer the indicator remains on,do you need special software to flash the unit ?Can anyone help with this.Thankyou. RE: Physio-Control - LifePak 500 AED
the battery and wrench icons are showing, but when the battery is taken out and put back in, and then the machine is turned on, the OK icon shows. The lithium battery does not expire for another 10 months. What could be the issue?
