Maintenance and Hygiene
ATTENTION: Before any attempt to perform maintenance activities with the Seiler Evolution Zoom
Microscope
, please read carefully and thoroughly the present User’s Guide. These tasks shall only be
executed by qualified personnel.
Switching bulbs during use (only for units with halogen bulb)
• In order to avoid undesirable interruptions in work when a bulb burns out, the Seiler Evolution Zoom
Microscope is provided with a redundant bulb, which is assembled and ready for use.
• Switching between bulbs is performed by turning a selection switch on the illumination box (Figure 2).
• It is recommended to replace the burnt out bulb as soon as possible.
Replacing a burnt out bulb (only for units with halogen bulb)
• Shift the main switch on the control panel to OFF (Figure 5) and disconnect the power plug from socket (Figure
8).
• Check whether the equipment is hot. If so, wait a few minutes (approximately 15 minutes) until it is cooled.
• Loosen 4 screws holding the illumination box cover, and remove it (Figure 15).
• Release 2 electrical sockets in which the halogen bulb is inserted (Figure 15).
• Release 2 screws from the bulb housing (Figure 15).
•
Remove the bulb housing by pulling it out (slide fitting) (Figure 15).
• Replace the burnt out bulb and reassemble the illumination box (Figure 15).

ATTENTION: Never touch the bulb.
PLEASE NOTE: When reassembling the device, do NOT invert the position of the power sockets. If this
happens, light will be emitted from bulb, but the position of the optical fiber inside the illumination box will NOT
match the light bulb in operation. As a result, light will NOT go through the optical fiber and, thus, the surgical
field will NOT be lighted. The correct operation of the equipment must be verified by test immediately after light
bulbs are replaced.
