Cordless Mouse (250-2006) Battery Replacement Faxback Doc. # 2766 With AC Adapter The mouse's battery typically lasts for several years under normal conditions. However, if the mouse does not work after a full recharge, you might need to replace the battery. The mouse's battery is not user-serviceable, and it must be replaced by a service technician. When you can no longer recharge the battery, bring your cordless mouse to your local Radio Shack store for battery replacement. (LB/all-9/14/94)
