Care to be Taken During Handling

Before Using Your Camera

  • When traveling, take the Worldwide Service Network listing that is included in the package. This will be useful if you experience problems abroad.
  • When the camera has not been used for a long time, confirm that it is still working properly, particularly before taking important pictures (such as at a wedding or when traveling). Contents of the recording cannot be guaranteed if recording, playback, or transferring your data to a computer, etc. is not possible due to a malfunction of your camera or recording media (memory cards), etc.

About the Battery and Charger

  • To keep the battery in optimum condition, avoid storing it in a fully charged state or at high temperatures.
  • If the battery is left inserted and the camera is not used for a long time, the battery will over-discharge and shorten the battery’s life.
  • Charging the battery a day before use or on the day of use is recommended. 
  • The AC plug cord provided with this camera is developed exclusively for the battery charger D-BC90. Do not use it with other devices.

About SD Memory Cards

  • The SD Memory Card is equipped with a write-protect switch. Setting the switch to LOCK prevents new data from being recorded on the card, the stored data from being deleted, and the card from being formatted by the camera or computer.
  • The SD Memory Card may be hot when removing the card immediately after using the camera.
  • Do not remove the SD Memory Card or turn off the power while the card is being accessed. This may cause the data to be lost or the card to be damaged.
  • Do not bend the SD Memory Card or subject it to violent impact. Keep it away from water and store it away from high temperatures.
  • Do not remove the SD Memory Card while formatting. The card may be damaged and become unusable. 
  • Data on the SD Memory Card may be deleted in the following circumstances. We do not accept any liability for data that is deleted if
  1.  the SD Memory Card is mishandled by the user.
  2. the SD Memory Card is exposed to static electricity or electrical interference. 
  3. the SD Memory Card has not been used for a long time
  4. the SD Memory Card or the battery is removed while the card is being accessed.
  •  If the SD Memory Card is not used for a long time, the data on the card may become unreadable. Be sure to regularly make a backup of important data on a computer. 
  • Format new SD Memory Cards. Also, format SD Memory Cards previously used with other cameras.
  • Please note that deleting data stored on an SD Memory Card, or formatting an SD Memory Card does not completely erase the original data. Deleted data can sometimes be recovered using commercially available software. If you are going to discard, give away, or sell your SD Memory Card, you should ensure that the data on the card is completely deleted or the card itself is destroyed if it contains any personal or sensitive information.
  • The data on your SD Memory Card should be managed at your own risk.
