If the emergency lamp indicator is lit immediately after the light source is turned
ON, it is highly likely that the installed emergency lamp is burned out or out of
order, contact Olympus.

Checking the lamp life
Check the lamp life indicator.
The total working hours of the examination lamp are displayed by this
lamp life indicator.
If the “500 h” indicator is lit (see Figure 4.4), replace the examination lamp
with a new one as described in Chapter 6, “Lamp Replacement”.
The examination lamp should be replaced as soon as it
appears to darken, even if the “500 h” indicator is not yet lit.

Inspection of the filter function
The filter function makes it possible to place a filter of your choice in the light
path for special applications. For instructions on selecting and installing a
special-purpose filter, see Section 5.3, “Using the filter function”.
S
Do not use the filter function when no filter is installed in the
filter disk. Confirm that the frame of a special-purpose filter
is pushed into the filter disk as far as possible. Otherwise,
equipment damage can occur, or light emitted from the distal
end of the endoscope can cause burns.
S
While inspecting the filter function, do not touch anything
inside the lamp chamber. The lamp cover and everything
inside is extremely hot and may cause burns.
Do not touch the emergency lamp, reflector or filter. Natural
skin moisture from your fingers can cause cracks and
damage the light source.
