3-1 Replacing the halogen lamp of the microscope
Precautions to be followed when replacing the halogen lamp during
observations or right after turning it off:
During observations or right after turning the halogen lamp off, the
lamp, lamp housing, and surrounding parts are very hot. Before
replacing the lamp with a new one, set the power switch to O (OFF),
pull out the power cord, and wait for a while until the lamp, lamp
housing, and surrounding parts cool off.
Do not directly touch the lamp. If a fingerprint or other substance gets
on the surface of the lamp, wipe it off using a soft cloth to prevent the
lifespan of the lamp from shortening or the lamp from bursting.
Use a 12V halogen lamp 100WHAL-L (7724 made by Philips).
1. Loosen the securing screw (1) on the top surface of the lamp housing using the
hex screwdriver provided with the microscope system.
2. Remove the lamp cover (2) by lifting it up.
3. While pressing and holding down the lamp locking lever (3), hold the new halogen
lamp (4) wrapped with a piece of gauze or something similar, and horizontally
insert the pins (5) until it butts up against the socket (6). Gently release the lamp
locking lever (3) to secure the new halogen lamp in position.
4. Replace the lamp housing, and tighten the securing screw (1) while pressing it
downward.
