= Check the battery direction should be correct.
= Check the battery if have enough power. If not, then need change to use another 2*AAA batteries
= Reduce the distance of the receiver and the keyboard Working Environment The receiver should be far away from the Monitor, outside disc driver or other electronic products, in order to prevent the radio disturbance produced by other electronic products the suggested distance is above 20 centimeters The radio signal can penetrate lignin, glass and so on the non-metallic objects, achieves 360 degree free transmit, but it can not penetrate the metal materials, so please do not put the mouse and the receiver onto the metallic tabletop, suggested distance is above 20 centimeters;Please be sure there is no big size metal between the mouse and receiver, otherwise the connection will be affected. Optical mouse is suitable for operating media wooden, paper or cloth, but not for the ratent, such as glass and smooth rubber. A mouse pad is needed in such environment. The standardized receiving distance we offered is under certain radio disturbance environment, the normal environment are better, the actual receiving distance is higher than standardized, but if mix-machine, motor, electric drill and other strong electronic equipments operating nearby, which may lead to slowly receiving or other abnormity. naa This device must not be co-located or operating in conjunction with any other antenna or transmitter. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation. Caution!
