camera. A screen will appear that says Cleaning image

Figure 5-7. Clean at startup/shutdown screens
Clean at startup/shutdown – For preventative dust control,

startup/shutdown cleaning:
▪ Clean at startup
▪ Clean at shutdown
▪ Clean at startup & shutdown
▪ Cleaning off

startup/shutdown cleaning modes. I can turn my camera on

be very brief when using this mode. Use these steps to choose
a Clean at startup/shutdown method (see Figure 5-7):
