Cleaning the lenses and reflectors
1. Lens cleaner
• Cleaning liquid:
Change the mixture ratio of alcohol and ether depending on
ambient temperatures. Make sure that the liquid evaporates
from the lens surface immediately after you rub it: This is the
best ratio. The more ether is used, the quicker the liquid
evaporates.
ambient temperatures. Make sure that the liquid evaporates
from the lens surface immediately after you rub it: This is the
best ratio. The more ether is used, the quicker the liquid
evaporates.
• Method:
Use well-washed bleached cotton cloth or cleaning paper
available on the market. Damp the bleached cotton cloth with
the liquid, and hold the lens sandwiched in the cloth with your
thumb and the index finger. Turn the lens and wipe the surface
clean from the center outward to collect dust. Be careful not to
rub the coated surface too strong.

Controlling the total operating hours of the lamp
The following control is carried out when the lamp has been used for 1900 hours and 2000 hours.

and the lamp LED indicator lights up in red.
When the 1900-hour point comes up during use of the unit, the “LAMP” display starts flashing in yellow on the
screen for 1 minute at the very 1900-hour point.
Now the lamp LED indicator changes from green to red.
