Title: MOUSE BALLS NOW AVAILABLE AS REPLACEMENTS

If a mouse fails to operate, or should perform erratically, it may be in need of ball replacement. Because of the delicate nature of this procedure, replacement of mouse balls should be attempted by trained personnel only.

Before ordering, determine the type of mouse balls required by examining the underside of each mouse. Domestic balls will be larger and harder than foreign balls. Ball removal procedures differ, depending upon the manufacturer of the mouse. Foreign balls can be replaced using the pop-off method, and domestic balls by the twist-off method. Mouse balls are not usually static sensitive, however, excessive handling can result in sudden discharge.

Upon completion of ball replacement, the mouse may be used immediately.It is recommended that each service technician has a pair of balls for maintaining optimum customer satisfaction, and that any customer missing his balls should suspect local personnel of removing these necessary functional items.
