How do you calibrate the TC-3020 to detect silver? I have installed new batteries, and it will detect nickels, pennies and newer coins but not silver.

How do I calibrate the Treasure Cove TC-3020? I cannot get it to detect silver at all. Have changed batteries and adjusted settings but no luck. I like the detector but am very frustrated.
