1. Using the Allen screwdriver provided with the microscope frame, loosen
the burner socket clamping screw @. (Fig. 1)
2. Loosen the burner clamping screws ³ and | and remove the transport
post. (For burner replacement, remove the used burner.) (Fig. 2)
3. Insert the + pole of the mercury burner ² into the + terminal and tighten
the + clamping screw ³.
Then loosen the – clamping screw | (marked UP). Insert the – pole of
the burner into the – terminal and tighten the – clamping screw |. (Fig. 2)
Be sure to use a USH102D burner (mfd. by Ushio Electric) or
HBO103W/2 (mfd. by OSRAM).
Be careful and avoid leaving fingerprints or dirt on the mercury
burner. Attached stain may cause distortion in glass which could
result in a ruptured burner. If the burner is contaminated, clean it
by wiping gently with gauze slightly moistened with absolute
alcohol.

} While aligning the exterior of the lamp housing with that of the socket, let
down the lamp housing vertically until it fits over the socket.
} For details on mounting the collector lens unit and the lamp housing on
the microscope frame, refer to the instruction manuals for the reflected
light fluorescence modules for the AX, BX, BX2, IX, etc., microscope
frames, respectively.
