Just purchased the Genius Traveller 9005BT, Optical (LED) Mouse, Blue tooth, Cordless, Black/Blue to use with a Samsung Galaxy Tab 3 10.1 - I’ve followed the instructions and went into settings/Blue tooth (I already have a Blue tooth keyboard paired), turned the mouse on then pressed and held the connect button under the mouse and started a scan but no new input devices are found.

Help would be most appreciated
