The camera shutter is stuck or is unresponsive
Make sure the lens is clean and nothing obstructs the shutter’s path. Use either microfiber or tissue and cleaner to carefully remove any debris, use compressed air around the lens and shutter area
Try interrupting the shutter by setting the shutter speed as low as possible, then pulling out the batteries while the camera is still taking the photo.
The memory card cannot be accessed
The following lists the memory cards that have been tested and approved for this camera.
- SD Memory Card: Panasonic
- SDHC Memory Card: SanDisk, TOSHIBA, Panasonic, Lexar
- SDXC Memory Card: SanDisk, TOSHIBA, Panasonic, Lexar
Try using another approved memory card. First you want to turn off the camera, eject the memory card and then insert a new memory card. Make sure the card is inserted in the correct orientation otherwise you will get an error saying "unable to read card" on the LCD screen. Once the new memory card is inserted turn on the camera.
Turn off the camera, eject the memory card, and reinsert until it clicks. Make sure the card is inserted in the correct orientation. There is also a label on the camera showing which way the memory card should be orientated.
Format the memory card using the camera or a computer. Connect the adapter onto the end of your memory card that converts it into the full size SD or MMC card. If you need a adapter simply click this link- http://goo.gl/adqSot . Then insert your card into the card reader and plug in the USB cable into your PC. After several seconds your memory card will be identified and then you want to right click and select "Format". Once you do that a dialog should pop-up and you click "Start". By following these steps you should be able to correctly format your memory card
Note: Make sure to backup any files in the memory card.
- Remove any debris that may be stuck in the lens cover. Use compressed air or a blow dryer (set to cold setting) to dislodge any debris.
- Slip a thin piece of paper between the surface of the lens and its outer ring to dislodge any debris that may be stuck there.
- Hold camera with lens barrel facing down, and tap the lens barrel to dislodge any debris. Repeat with lens extended and retracted.
The batteries may be depleted, try putting in new batteries.
