The memory card slot feels tighter than usual. after i put in the memory card and turn on the camera, i get the message of "no memory card."

It's a lost cause. The A540 works with SD cards. While SDHC cards will fit into the slot, they are electronically incompatible and will not work in devices not designed for them. You need to stay with SD cards, 2GB and smaller.

The holder that holds your memory card is broken and needs to be replaced.

Take a small flash light and see if there is a part of a memory card in there, if there is cleaning it out would solve the problem. Also make sure you're putting the memory card in the right way. I've you've done that and it's still giving you problems try going into the menu's and formatting the memory card in the camera.

The images you take with your PDC 640 camera are stored on a removable 3.3V SSFDC or SmartMedia 2 MB memory card (also available in 4 MB and 8 MB). Note: You must insert the memory card before you can turn on the camera.

If camera beeps is enabled, the camera beeps if the card is not installed and displays the [ ] message on the Status panel.

To insert the memory card:
1. Make sure the lens cover is closed (the power is off).
2. Open the memory compartment on the side of the camera.
3. Insert the memory card into the slot (gold side of the card facing the front of the camera).
Make sure the card is pushed firmly into the slot. Note: The camera prompts you to format the memory card if it is not formatted. The camera displays the format menu on the LCD viewfinder. Press the button next to Format.
4. Close the memory compartment cover.

If you can, try using a different memory card. Else, your memory card contact terminals inside the camera may have become worn, causing the camera to not recognize the card once it is inserted.

Installing SD Memory Card

Your camera has a memory card slot that enables you to insert any "SD" compatible memory card up to 8BG. Adding a memory card will allow you to increase the capacity of your camera before you have to transfer photos and videos to your PC. Install the SD memory card as below:

1. Locate the Memory Card slot within the battery compartment.
2. Insert the Memory card into the slot in the correct direction. (see the sketch below)

1. Push the card in until you feel it "click" into position. The top of the card should be flushed with the surface of the camera. An icon will appear on the LCD screen after you turn on your camera.
2. Once the external memory card is inserted into the camera all the images taken with the camera will be stored on the card.

Note:

1. Limited internal memory is provided for test images. The image will be deleted when camera power is turned off. Please download the images before power off .SD memory card is required for normal use.
2. An external memory card is required for normal use. Your camera supports any compatible SD memory card (up to 8GB).
3. If there is a photo in the internal memory when you insert the card into your camera, a "Copy to card" message will appear on the LCD with Yes or No options. On selecting 'Yes' the photo will now be copied to your card.
4. Formatting will delete all data on the SD memory card including protected data.

1. Don't remove the SD card during formatting as this may damage the card and render it unusable.
2. When your card is full, download the media on the SD card to your PC and delete the photos and videos from it in order to continue using your

OK, if the memory card itself is locked, you might sometimes get this error code. All you need to do is to take out the memory card and switch the lever on the left side to the unlock.



If the error is still displayed after you did the above, you might want to try the card in another camera.

If the card works in another camera . the problem is with your card reader in your camera.

If you open you sd slot and look inside with a sharp light , you should be able to see on the left side of the slot there is a little copper or spring steel lever switch. This switch work as follows:

1. When no card is inserted / no write protection , the switch is open and thus the protection is off.
2. When locked card is inserted , the tab is depressed and tells the camera that the card is lock.

Contrary to popular belief ,the little tab on the sd card is not an electronic switch and does not physically influence the card operation itself. If you put a locked card into a camera without a sd lock switch , you would still be able to use the card normally.

It is incredible difficult to fix this switch because of space limitations in the sd card. Look into the sd slot and if you can see the switch , use a needle to pull the little tab down toward the base of the camera by about 2mm or until it works being careful not to bend it.

If this does not resolve your problem , there might be a short in the switch circuit and the camera will need to be disassembled to resolve this error. This should cost no more than $50.

Thank You.
