5. Replacing Prism (cont’d.)
6. Replacing L-823 Cordset
2. Replace with new lamp and new filter.
NOTE: See Figure 6-6. To optimize photometric output, make sure
that the lamp is correctly positioned with the arrow pointing up.
Never touch the bulb of the lamp with your bare hands. It will
reduce the lifetime of the lamp considerably. Should it happen,
clean the bulb with alcohol.
3. See Figure 6-5. For the red or green optical support assembly, put the
filter spring (4) and filter (3) back in. Make sure the curved part of the
filter spring faces the filter.
4. Put the two parts of the lamp clip (6) in their respective notches on the
lamp holder assembly.
Refer to Table 6-4 for parts referred to in Figure 6-10.
