indicator flashes. If the overheated status
continues more than 2 minutes, the lamp is forcibly turned off.
→
Check for the following problems.
• Has the cooling fan stopped?
• Is the air intake port blocked?
• Is ambient temperature high due to insufficient ex-
haust from the airtight enclosure?
* When the temperature inside the unit lowers, the
alarm will be cancelled.

Lamp change
When the accumulated lamp operation time reach-
es 4000 hours (L8253:3000 hours) (lamp lifetime),

The unit can be used for some time after this indi-
cator starts flashing, replace the lamp with a new
one as soon as possible.
After replacing the lamp, be sure to reset the accu-
mulated lamp operation time.
When the accumulated lamp operation time reach-
es 5000 hours, the lamp is forced to turn off for the
sake of safety. (Unless the accumulated lamp oper-
ation time is reset, the lamp will not turn on again.)
Preparation prior to Operation
■
Connecting the Light Guide
q
Loosen the light guide fixing screw on the rear panel’s light guide connection aperture.
w
Insert a light guide all the way into the aperture, then retighten the screw.
●
Do not touch the end face of the light guide. Dirt at-
tached on it will reduce the amount of transmitted light.
●
Always handle light guides with care, as they are deli-
cate and may break if dropped or if bent to an exces-
sive angle. Never bend to a radius of less than 10 cm.
●
Do not use the light guide with the protection cap
attached to the end of the light guide. The cap would
melt as the end face of the fiber is deteriorated by
heat, and cause the output intensity (volume of light)
to reduce. If it has become dirty, wipe it with a gauze
(soft cloth) soaked with alcohol.
●
Always turn off the power supply switch to the main
unit before connecting the power supply.
■
Connecting the Power Supply

CAUTION
●
Do not touch the end
face of the light guide
with bare hand. If it has
become dirty, wipe it
