Most likely, this will effect tracking of pointing devices or the range of the device. To make sure that your keyboard transmits and receives properly, refer to the following instructions: 1. For optimal performance, place the receiver at least 8 inches (20 centimeters) away from other electrical devices, such as the computer monitor, Zip drives, speakers…etc. 2. The effective distance of wireless keyboard should be no farther than 26-33 feet (8 -10 meters). This will ensure optimal communication between the keyboard and the USB receiver. NOTE: You should always get at least a 4 meters range. If you find that your cordless device gets less than 4 meters range, please replace the batteries with a fresh set, perform the synchronization procedure for the keyboard and test the range again. If the range is still below 4 feet, please test your device on another system, preferably in a different environment. If you find it gets the same range on another system, please contact A4 TECH support to obtain information about a warranty replacement. However, if the range improves on another system, then it may be an environmental variable. Use the suggestions above to resolve the environmental interference issue. Keep 8 inches
