What should I do if the SD card doesn’t work properly on my camera?

It is recommended that the SD card be tested before using it. If you encounter issues such as being unable to format and recognize an SD card, rebooting, clearing the app cache, re-inserting, and changing another card may help.

Please note the following notifications before attempting the troubleshooting suggestions below:

1. Some SD cards may not be suitable for use in cameras. Please make sure the SD card inserted in the camera is compatible with the MERCUSYS camera. For more details, please refer to What type of microSD card does MERCUSYS Camera support?

2. SD cards have a limited lifespan and may become faulty over time, so please replace them regularly.

Here are some suggestions:

Note: Ensure your camera firmware and app version are up-to-date before you try the suggestions. Before initialization, remember to back up important files.

Step 1. Turn off the camera, remove and re-insert the SD card several times. Then, turn on the camera and check if the SD card can be formatted/recognized.

Step 2. Clear the app cache and format the SD card in the MERCUSYS APP again. Check if it works.

Step 3. Try another High Endurance microSD card.
