Maintenance
➀ If at any time the Light Source fails to come on,
remove the top cover of the Light Source by re-
moving the four screws as shown in Figure A3,
and replace the light bulb. If problems persist,
contact PASCO scientific.
➤ ➤ ➤ ➤ ➤NOTE: The light bulb should be replaced
only with the following replacement part:
Light Bulb: #211-2 (Available at automotive
stores, or from PASCO: part # 526-016.)
➁ To avoid scratching component surfaces, clean
lenses and mirrors only with lens tissue—lens tis-
sue can be purchased at any camera supply store.
➂ Care should be taken not to scratch or abuse the
surface of the magnetic pads. Should the surfaces
become dirty, use only soapy water or rubbing al-
cohol for cleaning. Other solvents may dissolve
the magnetic surface.
