I was out shooting my 501CM with its new CFV-50 back when a flashing yellow box with the word BACK in black letter appeared on the LCD screen. I turned off the back and turned it on again--and again the flashing yellow box with BACK in it.
I looked through the manual and could not find any reference to this.
Is it an error message?
If so, what does it mean?
Thanks.
