The USAlert WatchDog Pager Battery Cover is a standard part of the WatchDog housing and holds the batteries in place while also providing protection for the battery compartment. Individual covers can be ordered separately if damage occurs to the original part. The black polycarbonate cover is attached to the back of the WatchDog housing with a metal screw, but over-fastening the screw or excessive wear and tear to that part of the housing may at times damage the plastic. Since the Battery Cover can be easily removed and replaced, shipping the entire pager back for repair is not necessary. Both USAlert WatchDog and WatchDog LT pagers use the same interchangeable Battery Cover.
