This error comes from either the camera getting to hot or the batteries being depleted. To relieve this issue let the device sit for a while. If the error persists after letting the device sit, replace the batteries.

Checking the forums this seems to be a common error for this device but there is another reason this may happen. If the battery lid gets loose, the batteries are not held in tight. The extra space causes the batteries to arc which increases the heat inside of the camera. This issue maybe be relived by holding pressure on the side of the camera where the batteries compartment is. This pressure will create the correct contact that is needed for the device to work properly.
