5. Remove the lamp assembly from the bracket by slackening the thumbscrew
and pulling the lamp mount vertically upward.
Save the thumbscrew for use with the new lamp assembly.
6. Unpack the new lamp assembly, taking care to hold it only by the metal mount
to prevent fingermarks on the bulb.
7. Slip the slot at the base of the lamp mount over the stud on the bracket in the
lamp compartment and then secure with the thumbscrew.
8. Carefully push the ceramic connector firmly onto the pins on the base of the
lamp.
9. Wipe the bulb with a soft cloth moistened with alcohol to remove dirt, since
this would otherwise be burned in when the lamp is hot.
10. Replace the lamp baffle using the reverse of the procedure described in step 3.
11. Replace the lamp compartment cover.
This completes the halogen lamp replacement procedure.
