Steady shot warning A5100

[Sk22]

Hi , I recently got a Sony a5100.I did not use before this kind of camera ( only compact camera I used).

I have a problem with this warning . When I turn on the camera sometimes it come or sometimes when i do zoom in / zoom out and also screen start to blinking in this situation ( being black and then come back ) . My camera has problem? Or I adjust something wrong ? Is it possible to remove this warning with special adjustment ?
