Monitor showing SD Card cannot be used Nikon Coolpix 3700

SD cards have a slide switch along one edge. The position farthest from the metal contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card.

Your camera will accept a maximum SD card capacity of 1GB. It simply isn't capable of handling anything of a larger capacity and in particular is incompatible with the more technically advanced SDHC cards.

Your fix is to either replace your camera with a later model or to stick to using SD cards with a maximum 1GB capacity.

The 5900 uses SD cards. The 4GB card you have is actually an SDHC card and will not work in the 5900. You'll have to stay with cards 2GB and smaller.

Hi,
For the message that show's on your camera here's is what your need to do. 1. Remove the memory card and check for the physical lock toggle.
2. Toggle the lock on and off.
3. Try blowing on the memory card and the memory card port so it will be cleaned somehow. here is the picture of the lock toggle of the SD memory card

Use a good antivirus software to scan the SD card. Your SD card could be infected.

Hope this helped.

I'm assuming you're formatting the card in the camera and not in the computer. Try this...remove the card and battery...press all the buttons....leave it alone for 20 minutes...insert the card and then the battery...turn it on.

Hi I found this info on the Nikon Australia website:

"System Error" or "Lens Error" message in LCD monitor Question My COOLPIX camera displays a "System Error" or "Lens Error" message. What should I do? Answer Having a "System Error" or "Lens Error" message displayed on the camera's LCD monitor would generally indicate that your camera needs servicing. A System Error is a general error which can be caused by many things: lens problem, CF Card problem, general camera failure, etc. To troubleshoot, please try the following:

1. Use the memory card that originally came with your camera (or a Nikon approved card).
2. Remove and replace the battery.

On the other hand, a Lens Error generally means that an error has occured during the lens operation. To troubleshoot, please try the following:

1. Turn off the camera.
2. Remove and replace the battery.
3. Turn on the camera.

Seems you may just have to remove and replace the battery - sort of like a Windows Restart to fix a computer problem! - this would reset your camera's memory.

Hope this helps.

Change your USB option to Mass storage.
