5.3 Replacing the Halogen Lamp
ALWAYS DISCONNECT YOUR EQUIPMENT BEFORE DOING ANY REPAIR.
Do not touch the glass envelope of the lamp during installation. Keep the protective
sleeve or bag of the lamp during installation and remove it right after installation.
LAMP AND LAMP HOUSING MAY BE HOT TO THE TOUCH.
•
Switch off the microscope.
•
Disconnect the power cord.
•
Wait until the housing and bulb have cooled
sufficiently.
•
Open the lamp access door. The FL150 has a
plastic door with latch and the FT190 has a
metal door with two thumbscrews.
•
Move the ejector lever as shown below to pop
the bulb out of the socket.
•
Remove the defective lamp and push the new
lamp into place being sure that the pins and
the glass reflector are squarely aligned in the
socket or premature bulb failure will result.
•
While placing a new lamp into the socket,
avoid touching any the glass part. Notice the
bulb is wrapped in plastic. Use it to avoid
touching the glass parts during installation.
•
Close or re-install the lamp cover door.
•
Reconnect the power cord and switch on the
microscope to verify proper illuminator operation.
