5-5 PROCESSOR FUNCTIONS

NOTE
-Check the lamp life hour meter on the rear panel
●
frequently, a lamp with 200 hours or more should be replaced
before beginning a procedure.
(1) LAMP
Turn on the power switch to ignite the lamp. If the lamp fails to
●
ignite, the lamp service LED lights. Turn off the processor,
wait 60 seconds and turn on the processor. If the lamp still fails
to ignite, do not attempt to perform an endoscopic procedure.
Contact your local Pentax service center.
NOTE
-After igniting the lamp, allow the processor to run for
ten (10) minutes. This will allow the color temperature to
stabilize and ensure accurate color.
When the procedure is completed, the lamp can be shut OFF by
turning the EPK-700 power OFF. Wait 5 minutes before
turning on the Lamp again.
(2) BRIGHTNESS
Brightness functions can be controlled from either the processor
front panel control buttons or the endoscope control buttons.
(See section, Endoscope control buttons).
Select the desired brightness control mode, AUTO or MAN,
●
using the brightness control switch on the processor front panel
or the endoscope control buttons.
AUTO = Automatic brightness control, where the video signal
of the endoscope will automatically maintain the brightness
level selected by the brightness adjustment buttons. The switch
will beep when pressed and the AUTO indicator will light
when the AUTO mode is selected.
If the AUTO brightness mode is selected, select the desired
●
brightness level and the light measurement method, AVE or
CENT, using the light measurement switch on the front panel
or the endoscope control buttons.
AVE = The brightness level is automatically adjusted with
respect to an averaging of the brightness of the video signal.
CENT = The brightness level is adjusted with respect to the
brightness of the center of the screen.
The switches will beep when pressed and the AVE or CENT
label will light when either is selected.
