there be not instruction . after mess around with it , I figure out to press the fn+alt +0 to get it to connect -lrb- blue light come on -rrb- . it work on my ipad -lrb- 1 -rrb- , but refuse to connect to my ipod -lrb- 2nd gen -rrb- . it be light weight and small , but cheaply make . for the price , I can not complain . however , for a few more buck I be probably better off with a better model .
