Maintenance
Notes
• When the CALL button is pressed, the “Lamp
time” (the approximate amount of time the lamp
has been used) will be displayed. 
• The lamp should be replaced if the total working
time exceeds about 1,500 hours.
When the “Lamp time” is displayed as 1500 hours,
the icon 
 and a message appear. They will
disappear when you do some operation.
• Attach the lamp cover firmly after replacing the
lamp. If it is not set correctly, the power will not
turn on.
• Use a new lamp when replacing it.
• The lamp is made of glass and is very fragile. Do
not touch the lamp with your bare hands and do
not jolt or damage it. Do not try to use an
exhausted lamp.
A small amount of inorganic mercury harmful to
environment is used for the lamp. Dispose of the
exhausted lamp according to the rules of your
area.
