View Full Version : Full backup of System files

09-04-2014, 01:53 AM

I have recently acquired access to an RV7 with a dual AF-3500 non 's' CPU setup.

After several flights first one and now the other EFIS units no longer keep the time/date settings. Both the AF-3500 come into the five year old bracket and from the forum I can see that the BR-1255 battery needs to be replaced.

I have the PDF that details how to replace the battery however I am not familiar enough with the process of obtaining a Full Backup of the System Files that is recommended before changing the battery.

I have the User And Installation Manual Version 7.2 but don't see a reference to doing the backup. Is there a technical document for doing the backup or please can someone point me to where I should be looking for the information in the manual?
