Precautions on lamp unit replacement
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*
1
, although the lamp
may become dead (will not light) before 2 000 hours*
1
is reached depending on the characteristics of individual
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.
The risk of the lamp bursting increases after 2 000 hours*
1
of operation, so the lamp unit turns off automatically.
After
1 800 hours*

The indication appears for 30
seconds or until any control button
is pressed.

The indication will not disappear
unless a control button is pressed.

This is the operating time if the lamp has only been used at the LAMP POWER “HIGH” setting. If the lamp
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).

This is the operating time if the lamp has only been used at the LAMP POWER “HIGH” setting. If the lamp
has only been used at the LAMP POWER “LOW” setting, the operating time is 2 700 hours. When the lamp
has been switched from LAMP POWER “HIGH” to “LOW”, the cumulative operating time from the
conversion formula below will be 1 800 hours.
Lamp operating time = LAMP POWER “HIGH” operating time + (LAMP POWER “LOW” operating time x 2 ÷ 3).
• It is not possible to turn on the power unless two lamp units are installed.
Note
WARNING!
Before replacing the lamp, be sure
to disconnect the power cord plug
from the wall outlet.
