the filter sliders for reflected light illumination" on page 39.

· Do not turn OFF the burner for two hours after turning it ON
because the burner's lifetime will be shortened.
· When turning ON the mercury burner again, wait until
the vapor of the mercury burner is cooled down and
devolatilized. Wait approx. 10 minutes and turn it ON.
· If you open the lamp housing while the burner is turned
ON, the system stops supplying the power for safety. In this
case, set the main switch to
(OFF), wait 10 minutes or
more and turn it ON. Be sure to wait until the lamp housing is
sufficiently cooled down before opening the lamp housing.
