CAUTION--HIGH VOLTAGE: Do not open the light
source with the unit plugged in.
Maintenance
The light source lamp, when used correctly (see the note on
the front panel of the unit), can be expected to provide
14,000+ hours of trouble free operation. However, if the
light at any time fails to come on, first check the fuse on the
front of the light source case. If the fuse is not blown, you
may need to replace the lamp. In rare cases, the problem
may be with the ballast. However, ballast replacement
should be performed only by experienced personnel. If the
fuse is intact and replacing the bulb does not restore opera-
tion, we recommend you return the unit to PASCO scientific
for repair.
Only the following replacement parts should be used:
