Error message on D70 freezing camera operations

Hello,
I got this info from Nikon for D70...
When you see Err on the control panel, LCD monitor or viewfinder of your digital camera it refers to a camera malfunction. Try the following:

1. Remove all accessories from the camera.
2. Install a freshly charged battery into the camera.
3. If your Nikon camera offers resets such as the two-button reset or a hardware reset please follow those instructions provided in the product manual.

If these steps do not resolve the Err message we recommend having a Nikon Authorized Repair Technician evaluate the Nikon camera.
Hope this be useful for you to resolve problem.

I had the same problem as above, tried everything, then i changed the battery for a fresh charged one and used the 2 button re-set. fantastic, many thanks, It worked for my D70s, Regards Jedstone
