xviiDisposing of Data Storage DevicesPlease note that deleting images or formatting memory cards or other datastorage devices does not completely erase the original image data. Deletedfiles can sometimes be recovered from discarded storage devices using com-mercially available software, potentially resulting in the malicious use of per-sonal image data. Ensuring the privacy of such data is the user’s responsibility.Before discarding a data storage device or transferring ownership to anotherperson, erase all data using commercial deletion software, or format thedevice and then completely refill it with images containing no private infor-mation (for example, pictures of empty sky). Wi-Fi settings can be reset todefault values by selecting Wi-Fi > Wi-Fi connection type > Reset Wi-Fi set-tings in the setup menu (0 124). Care should be taken to avoid injury whenphysically destroying data storage devices.Temperature WarningsThe camera may become warm to the touch during use; this is normal anddoes not indicate a malfunction. At high ambient temperatures, afterextended periods of continuous use, or after several photographs have beentaken in quick succession, a temperature warning may be displayed, follow-ing which the camera will turn off automatically to minimize damage to itsinternal circuits.
