lens cleaner.
•The lens is easily scratched, so do not rub it with hard objects,
or strike it.■Main unit cleaning•Clean the main unit after unplugging the power cord.
•Wipe dirt off the main unit gently with a soft cloth.
•If the soiling is severe, dip the cloth in a neutral
detergent diluted in water, wring well, and gently wipe
off the dirt, then finish up by wiping with a dry cloth.●Replacing cooling fans
To maintain the performance, it is recommended that cooling fans should be replaced
about every 2 to 3 years. Consult with your dealer for details.
