Precautions on lamp unit replacement
Remove the power plug and confirm that the surroundings of the lamp unit have cooled off.

For disposition of used lamps, request an industrial waste disposal contractor.
If you continue to use a lamp after the replacement time, the lamp may break.
Philips screwdriver is necessary when replacing a lamp unit.
Take care not to slip your hand when using a screwdriver.
Note
• It is not possible to turn on the power unless two lamp units are installed.
Timing of lamp unit replacement
The lamp units are consumable parts. The lamp brightness decreases gradually as the cumulative operating time
increases, so periodic replacement is necessary. The replacement guideline is 2 000 hours*
may become dead (will not light) before 2 000 hours*
lamps and other factors such as the operating conditions and the installation environment. Therefore, it is
recommended for the user to keep a spare lamp unit.

has only been used at the LAMP POWER "LOW" setting, the operating time is 3 000 hours. When the lamp
has been switched from LAMP POWER "HIGH" to "LOW", the cumulative operating time from the
conversion formula below will be 2 000 hours.
Lamp operating time = LAMP POWER "HIGH" operating time + (LAMP POWER "LOW" operating time x 2 ÷ 3).
