What does semaphore timeout mean?

Have you insert a memory card in it ? If we don't insert the memory card, pictures that have been taken will automatically saved in camera internal memory, and this memory usually have low capacity so we won't make many pictures because the memory will full in no time. The solution is insert proper memory card (kind and capacity).
If you have insert the memory card the camera shows that notification, it means you need to transfer your pictures data in PC so you can delete them and make more space in your camera memory card.

Hope this help and RATE please !

There doesn't seem to be a problem. The 3.7k means 3700, the k meaning thousand. If you were to take about 2700 pictures, you'll then see 999, then 998, and so on.

It could be, that what you are seeing, is the INTERNAL memory is being taken up with your pictures. Connect your camera to your computer with a USB cable and you will probably find them.

These cameras are on the list of the ccd problems.

problem is in memory card...i think. try with cleaning memory card contacts. use pure alcohol and small piece of cotton to clean dust or other dirt. if this not help, try some card reader to transfer images from camera to PC. try also with some other camera. it's possible memory card is damaged and you can't do nothing. try reinstall nikon software on your PC.

Check if your camera can support a 4G card. Some don't support than 2GB. if it supports, re-insert the card.
PS. If you have a card reader. Formatting once from your computer can help.

I would try another memory card. Do not buy cheap ones.

I also had the same problem - Finally solved it by reformatting the Memory Card on my Home Computer.
Note - It was not solved by using the delete pictures function on the V1253 Camera.
The problem only occured after I had used a friends Computer to delete pictures only from the Memory card.
Hope this helps!

Once you took pictures without a memory card, all pictures taken will automatically be saved on the INTERNAL MEMORY of the camera.
When taking pictures with a memory card, all pictures are just saved on the memory card itself.
If you are seeing 100-757 on the LCD screen. It means that there are already 757 pictures taken from the first time you've used the camera.
It is possible that some of the pictures are in the internal memory and some are in the memory card.

STEPS to DOUBLE CHECK:
1) Remove memory card out of the camera
- Turn on camera
- View pictures on the internal memory
by just pressing on the PLAY mode button
(lowest of the 3 little buttons)
- Pictures seen are just the ones saved on the internal memory

2) Return memory card back in the camera
- Turn on camera
- View pictures on the internal memory
by just pressing on the PLAY mode button (
lowest of the 3 little buttons)
- Pictures seen are just the ones saved on the memory card itself

*** If you want to transfer pictures on the internal memory of the camera to your MEMORY CARD, you just have to follow the steps below:
- Make sure there is a memory card inside the camera
- Turn on camera
- Press on PLAY mode button to view pictures
- Press MENU/OK button
- Keep scrolling to the right until you see COPY TO CARD
- Select YES using the arrow keys
- Press MENU/OK to confirm
* When you've done these steps, all pictures from the INTERNAL MEMORY of the camera will be copied to your MEMORY CARD but it depends on the space left on your memory card

** If still, you could not view the pictures, it's possible that the pictures are really gone when you have transferred the previous pictures to your computer.

** Once you have transferred pictures to your PC, and you have deleted those on your camera, the FILE NAME of the pictures will not start from 100-001 again unless you have reset the file name on the settings of your camera.

In example, i already have 256 pictures on my camera so the filename reads 100-256 for the last picture taken. And then i decided to transfer those 256 pictures to my PC and i deleted those immediately after being transferred. So, as i took another picture, FILENAME will start with 100-257 if i have not reset
the FILE NAME settings to 100-001.

Hope i've helped you enough.
