CAUTION

Do not reset the lamp usage time without replacing the lamp. The probability of a lamp explosion increases if the cumulative usage time of the lamp is more than 1500 hours.

If the lamp usage time is not reset, reset it by repeating step 5.

Be sure to reset the lamp usage time after replacing the lamp. Otherwise, the correct usage time cannot be known. When the display exceeds 1500 hours, the power to the lamp is forcibly turned off regardless of the lamp’s life.

•As a safety precaution, the lamp does not turn on unless the lamp unit cover is installed.

•The lamp unit sold separately comes with an air filter as part of the lamp kit. When replacing the lamp unit, be sure to replace the air filter as well. (See page E-56.)

•The lamp can be disposed as a regular household fluorescent light, follow the disposal procedure recommended by the local government.
