My linkststation went into EM mode without me doing anything, that was the initial fault. I had a power cut causing this fault, so I reinstalled the firmware as there wasn't one present just a ------ in the box on Nav. Then before I could complete this the fault light come on so everytime I turn on the unit after a few seconds the unit starts beeping and on my network discovery all that is said is " discovering with limited access " but the Nav can't find the linkstation
