Caution
• Never use a spray blower or a blower with a brush. The
CMOS sensor may be damaged. Do not wipe the CMOS
sensor with a cloth.
• Do not put the tip of the blower inside the lens mount area. If
the power is turned off during cleaning, this may cause
damage to the shutter, CMOS sensor and the mirror. Hold the
camera with the lens mount down while cleaning the sensor
so dust will fall away from the sensor when the blower is used.
• When the battery level is low, the message [Not enough
battery power remaining to clean sensor] is displayed on the
monitor. Install a fully charged battery. If the battery capacity
becomes low during cleaning, a warning beep will sound. In
this case, stop cleaning immediately.
