Just had to attend a call out on site, after a power down of the factory mains the AC700F forgot the uploaded program and requried a full station upload. This hasn't happened before on power shutdowns even when left offline for 1-2 weeks.
Theres no indication to say the batterys is dead and it will only be 4-5 months old in terms of working life.
Any probable causes?
Thanks in advance.

I suspect battery only, Check on PM 783 LCD is there black square blinking against BATT ?
Also check value of BAT variable in I/O editor of PM 783F?
If black square is blinking and BAT variable is 1 then there is insufficient battery, replace it.
Only incase of insufficient backup battery, controller had performed coldstart becuase of power off for more then 1-2 min and project data lost. else I can't see any possibility of project loss.
Which version of freelance(AC 700F) you are using with ? if it's V2013 then you can use SD card, good to take backup on SD card so incase of battery failer just boot controller with inserted sd card will work, no need to connect with CBF and download.
Hope that helps.
