Cleaning sensors
Adhesion of dust to a sensor may cause a false detection. Clean the sensors using an air duster.
• Use a non-flammable air duster. Read the cautions for use well, and be sure to keep the
descriptions in mind.
•
The sensors and metallic section are cooled by gas in the air duster, and may be temporarily
condensed. Wait for about five minutes.
