Memory Cards

  • Memory cards may be hot after use. Observe due caution when removing memory cards from the camera.
  • Turn the power off before inserting or removing memory cards. Do not remove memory cards from the camera, turn the camera off, or remove or disconnect the power source during formatting or while data are being recorded, deleted, or copied to a computer. Failure to observe these precautions could result in loss of data or in damage to the camera or card.
  • Do not touch the card terminals with your fingers or metal objects.
  • Do not bend, drop, or subject to strong physical shocks.
  • Do not apply force to the card casing. Failure to observe this precaution could damage the card.
  • Do not expose to water, high levels of humidity, or direct sunlight.
  • Do not format memory cards in a computer.

The Write Protect Switch

SD memory cards are equipped with a write protect switch to prevent accidental loss of data. When this switch is in the “lock” position, the memory card cannot be formatted and photos cannot be deleted or recorded (a warning will be displayed in the monitor if you attempt to release the shutter). To unlock the memory card, slide the switch to the “write” position.
