The figure below reveals the main features for this unit. On the front panel there is a fiber optic receptacle
with a retaining thumbscrew that locks the fiberoptic accessories into the receptacle. In manual mode, the
intensity of the lamp is controlled by the manual intensity adjustment potentiometer, and the power to the
lamp is controlled by the front panel Lamp enable switch. When the Lamp Enable switch is in the "0"
position, power to the lamp is removed, however the internal electronics and cooling systems are still
powered. Since this unit is equipped with a remote interface controller, the rear panel will have the
appropriate interface connector installed, along with a remote switch for selecting between manual operating
mode ("0") and remote operating mode ("1"). In the serial remote control mode the lamp enable and
intensity control are adjusted by digital commands through the rear panel connector. In this mode, the front
panel potentiometer and the front panel lamp switch are disabled. A lamp status indicator LED is visible on
the middle left side.
An IEC 320 power inlet module is located on the rear panel. This IEC 320 module provides an
internationally accepted power interface that can be used with a variety of power cords. The power entry
module contains the main power switch and the fuse box. The fuse holder allows the use of dual European
fuses (5x20mm). In order to access the fuses the power cord must be removed.
Lamp Replacement: Remove the 8 flat head screws on the cover and slide the cover towards the rear of the
unit and upward to access the lamp for replacement.
WARNING: Cover must never be removed before disconnecting the IEC 320 power cord.
The unit can be permanently mounted by removing the feet. This can be done as long as adequate airflow
below (intake) and in the rear (exhaust) of the unit is observed. Use M4 hardware and ensure a minimum of
10mm clearance under the base to allow for proper cooling. Never mount the receptacle pointing down.
