Operation
All the MI-150 series illuminators are equipped with a front panel manual solid state intensity control.
FAX: 508-682-2500
Press the ON(1)/OFF(0) rocker switch on the front panel to ON(1). The illuminator will light and is ready for service. The
illuminator intensity is controlled by the rotary control located on the front panel of the illuminator. The 0 position (when
control is turned fully counter-clockwise) corresponds to the lowest illuminator intensity. The 100 position (when control is
turned fully clockwise) corresponds to the highest illuminator intensity. NOTE: Continuous operation of the illuminator
at the highest intensity level will yield rated lamp life. Operating the illuminator at reduced intensity can result in
significantly extended lamp life.
Caution: The fiber optic interface (nose piece) runs at a very high temperature. Avoid contact during use and
when inserting or replacing light guide assemblies.

Lamp Replacement

1. Turn the illuminator intensity control fully counterclockwise (the 0 position) and run the illuminator with the fan for several
minutes. Wait until the nosepiece is cool to the touch.
2. Press the ON(1)/OFF(0) rocker switch to the OFF(0) position.
3. Remove the AC power cord from the AC power receptacle.
4. Open the lamp access door by depressing the small clip toward the rear of the
illuminator with your thumb or finger. Once the clip disengages from the illuminator
housing the lamp access will spring open several inches. The lamp access door will
open slightly more than 90 to allow easy access to the lamp and lamp socket.
Do not pry open the door with a tool. This may result in damage to the
illuminator housing or the lamp access door.
5. Check the lamp assembly to verify that the lamp and socket are cool before
proceeding. Caution: The lamp runs at very high temperatures and contact
with a hot lamp may result in severe injury.
6. Pull the lamp eject lever to remove the lamp from the socket.
7. Lift and remove the lamp from the lamp socket by grasping the rear of the lamp
adjacent to the lamp
8. Power pins.
9. Remove the lamp from the socket. Discard the old lamp.
10. Insert the replacement lamp into the lamp socket by aligning the lamp power
pins with the slots in the lamp socket. CAUTION: Do not touch the interior of the lamp reflector, the lamp envelope or the
lamp pins with your fingers. Touching the interior of the lamp reflector, the lamp envelope or the lamp pins will result in
significant shortening of the lamp life. Handle the lamp only by the exterior of the reflector or the area adjacent to the
pins.
11. Push the lamp gently into the socket to seat the lamp in the socket and lampholder.
12. Rotate the lamp access door toward the illuminator housing and gently press the lamp access door to cause the door clip to
seat into the housing and secure the door.
