WARNING
CAUTION
Replacement of Consumable Materials
1) Replacing the Lamp
• To avoid electrical shock or damage to the instrument, turn off the power switch
(turn to ○) and unplug the power cord before lamp replacement.
• Use the specified lamp. Using a different kind of lamp may damage the
instrument or cause a fire hazard.
Specified Lamp: Halogen lamp 6V-20W (PHILIPS 7388 or OSRAM HLX 64250)
• The lamp is hot when in use. To avoid burn injury, turn off the microscope and
wait at least 30 minutes (until the lamp is cool enough to touch) before
attempting to change the lamp.
• Make sure that the contacts of the lamp and socket are not damaged before
installing a new lamp. If the contacts are damaged, they may cause poor
illumination or overheating.
• Insert the lamp’s contact pins fully into the socket holes. If the pins are loose,
the lamp could come loose or result in a contact failure, which will cause
overheating or smoke.
• Be sure to put the field lens unit back in place after replacing the lamp. Never
turn on the lamp without the field lens unit.
• Do not touch the glass part of the lamp using your bare hands. Wear gloves or
use a cloth when handling the lamp to protect the surface from fingerprints.
Wipe off any fingerprints or stains using a clean cloth moistened with alcohol.
Fingerprints will etch into the hot surface of the lamp and reduce the brightness,
damage the lamp or reduce its service life.
• Handle the lamp gently. Shocks and vibrations will damage the lamp or reduce
its service life.
