Hi,
I have 9 sets of these communication cables, Quick start up tool kit CD, quick reference guide and operator and service manuals.
The main thing is obviously the comms cable with a part number of 170-2120 RevA
They are for the Cardiac science Powerheart AED G3 9300A and 9300E.
They have never been used and are for sale on several sites for about £70.
Any questions please ask.
Thanks.
