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, heat, high levels of humidity, or direct sunlight.
[] The Write Protect Switch
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 can not be formatted and
photos can not be deleted or recorded (a beep will sound if
you attempt to release the shutter). To unlock the memory
card, slide the switch to the "write" position.
