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? Why would the downloaded data be incomplete when using the automatic download function on the Android WiFi SD App? Why does my Wi-Fi SD card have no Wi-Fi signal after used for a while on a Nikon camera? Technical Support If the answer can't help you, you can contact the Tech Support Department Get Started
