The camera is having trouble accessing the memory card. Try cleaning the contacts, both on the card and in the camera, and/or try a different card.

CHA flashing on readout screen.
If there are brackets around the CHR, it means the card is locked. SD cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card. If the switch is already in the proper position, slide it fully the other way and then back again.
If there are no brackets around the CHR, it means the camera cannot read your memory card. Try a different card.

Can you help me with
Follow the directions in the camera manual on page 200 for a hatfware reset. There is a button on the bottom of the camera. It is held down for a few seconds to reset the hardware. If that does not work, ir sounds as if the meter may have gone bad and further investigation by a qualified service tech would most likely be in order.

My computer (and my husband's)stopped
apologies if this message finds you long after posting this problem ,
but I am currently working through a backlog of problems that never got
answered and hopefully this info can still be of use if not now possibly
Please download Disc Digger HERE.
This is a free tool you can use that works very well and there is no
installation required, just run the program once you downloaded it.
you have connected the memory card to the computer via either the
camera or preferably with a usb card reader , run the program.
the program , select the dig deep option for accidentaly deleted files
or dig deeper for a formatted card. Then select the card you want to do
the recovery on and run the program.
The data will be displayed
and you can recover it from there. This will only work if the card has
not been used since the pictures were lost. Save the files to a location
on the computer hard drive and not back to the memory card as this will
overwrite the other pictures that still needs to be recovered.
Some of the properties of the files may become lost in the recovery but the pictures should be fine.
Feel free to ask if you need more assistance.
