Replacing The Lamp - Pentax EPK-P Owner's Manual

Replacing the Lamp

You can install one lamp to use and one spare lamp in the EPK-p.
Check the [1] and [2] indicator lights for [SERVICE] (lamp life indicator) on the front panel before you use the processor. If any
of the indicators are lit orange, follow the procedure below to replace the lamp of the corresponding number. The harness for
lamp 1 is white and the harness for lamp 2 is black.
The average life of the lamp is 50 hours.
If a lamp goes out, the lamp indicator will illuminate orange and "Please replace the lamp 1 (or lamp 2)" appears on
the monitor.

Confirm the lamp to be replaced, and align the lamp selection switch to the number of the lamp

Make sure the power cord is disconnected before you replace a lamp.

counterclockwise and remove the housing cover.

will be hot immediately after the processor is used.

Make sure the lamp corresponding to the number of the lamp to be replaced is at the front.

replacement base manually.

finger.
- Avoid touching the parts around the lamp immediately
after the power is turned off since it may be hot.
- The rotation direction of the lamp replacement base
differs depending on the positions of lamps 1 and 2.
When lamp 1 is at the front: turn clockwise
When lamp 2 is at the front: turn counterclockwise
2 Rotate the lamp replacement base until the lamp
corresponding to the number on the lamp you want to
replace comes to the front, and the base comes into contact
with the stopper.

matches the number selected for the selection switch.
