How come when I turn on my Olympus OMD EM-5, I can't see the Wi-Fi signal from my Wi-Fi SD card? Category : Network Connection / Data Transmission The power-on voltage of the Olympus OMD EM-5 sometimes rises too slowly, which can prevent the Wi-Fi signal from appearing. We suggest that you turn the camera on first and then insert your Wi-Fi SD card. Is the answer helpful? Related Why do I need to format the memory card before using it for the first time?
