- 3 - Wireless Range Any electrical device, such as the computer monitor, Zip drives, speakers, etc., can cause interference with the wireless keyboard. 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
