Hi,
I have this defibrillator and i am always adjusting the hour, day and year... I enter the configuration menu and i adjust, but a few hours later (some time is just a matter of minutes) the hour, day and year is already wrong... something like:
30-May-2002 and the hour: 30:28

Does anyone have the same problem? How can i fix this?
Thanks

I know of this model but not in detail. I would guess a flat battery but some clock chips have it built in so you have to replace th whol chip.

Does anyone have the schematic?

Hi,

Change the Renata backup battery.

hi,

The Renata Battery is discontinued

I applaud your approach.

But regarding Renata ... surely there is one in there somewhere?

In portugal i can't get one equal

What is the battery number?
Robert

What is the voltage? (2.4 volts?)

And which "chemistry"? (Ni-MH?)

Not to mention:- which "package" (shape, layout, number of pins, etc.)?

Does anything here strike a light?

cardioaid MC+

Having just checked out the above mentioned URL (better late than never) I can confirm that it (still) makes available a 53 Meg .rar* file that unpacks into many (97 in fact) .jpg files - one per page from the manual.

It covers the Cardio-Aid MC, MC+ and LS from the happy days circa 1993. But not much in the way of schematics, unfortunately.
